Cfl Vs Nfl Rules
- In the CFL, the uprights are located at the goal line, rather than the back of the end zone. This rule adds a lot more field goal attempts, and could add a lot of excitement to the end of games.
- The CFL features many rules that differentiate it from the bland, American-style game. The NFL has a 40-second play clock. Half the time when I’m watching the NFL, I’m sitting around waiting for something to happen.
- Canadian / CFL teams playing American / NFL teams. This is is probably the most interesting of the possibilities since some accomodation has to be made for the difference in rules. The following is a picture of a plaque in the Profession Football Hall of Fame in Canton, Ohio that lists some (but not all) of these games.
The league that would become the NFL was founded in 1920; it based its rules on the collegiate game and followed those rules for its first 12 years. In 1932, the NFL broke ranks on a few rules and appointed its own Rules Committee, charged with developing changes independent of the colleges; the league would publish its first independent. In American football, Canadian football-type singles are not used.Receiving teams are allowed to down the ball in the end zone for a touchback, and kicking the ball out of bounds through the end zone also results in a touchback; in either case, the receiving team receives possession of the ball at either its own 20- or 25-yard line, depending on the specific level of play.
Imagine the NFL if the rules of play had never changed:
A quarterback can’t throw a pass unless he’s at least 5 yards behind the line of scrimmage. The offense begins some plays just a yard from the sideline and is penalized for throwing more than one pass during a series of downs. Player substitutions are prohibited. No communication from the sideline is allowed. Players from both teams grab their opponents’ facemasks at will.
Of course, that’s not how professional football is played today. Throughout the history of the NFL, the custodians of the game not only have protected its integrity, but also have revised its playing rules to make the contests fairer, safer and more entertaining. Time and again, the league has shown that it is open to ideas generated by any source or circumstance — or even by new technology — if it believes that the changes will improve the game.
Now spearheaded by the Competition Committee, the NFL rules-changing process is systematic and consensus-oriented. Widely agreed-on ideas may be quickly approved and implemented. Others take years to make it from a proposal to the field. Some evolve over time. And although the vast majority of proposed rule changes are never adopted, all are carefully considered.
The evolution of the league’s kickoff rules shows the process at work.
Evolution of the Kickoff
In 1974,
owners approved the Competition Committee’s recommendation to move the kick from the 40-yard line to the 35-yard line.
Part of a broad package designed to rev up the game, the change was made to produce more exciting returns. And it worked: Kickoff return rates immediately jumped from 75 to 92 percent.
In 1994,
after statistics showed the rate dropping precipitously, the league moved the kick to the 30-yard line.
That boosted the return rate to 88 percent in the 1994 season from 68 percent the previous year.
In the 2000s,
kickoff-play injuries became a concern.
The committee examined videotape to determine the causes of those injuries and found one source to be “wedges” of three or more blockers. In 2009, the owners approved a committee proposal to ban return-team players from linking up in this formation. A few years later, however, the committee rejected the idea of a ban on two-player wedges.
In 2011,
the league moved the kicking line back to the 35-yard line to reduce the return rate; it also limited running starts by the kicking team.
The number of concussions on kickoffs dropped by 40 percent during the 2011 season, and the return rate fell from 80 to nearly 50 percent.
Between 1974 and 2011, the NFL moved the kickoff line three times. Each adjustment was carefully considered and made solely in response to circumstances and trends at the time.
In 2009, the rules were modified to prevent three or more defensive players from forming a wedge to block for the return man on kickoff returns. This change, aimed at reducing injuries, came about only after the Competition Committee members had meticulously examined hours of film of kickoffs.
Evolving Slowly but Surely
In the league’s early days, the rules-change process evolved slowly. The league that would become the NFL was founded in 1920; it based its rules on the collegiate game and followed those rules for its first 12 years. In 1932, the NFL broke ranks on a few rules and appointed its own Rules Committee, charged with developing changes independent of the colleges; the league would publish its first independent rulebook before the end of the decade.
Today, the Competition Committee — the successor to the Rules Committee — is an nine-member group of team executives and coaches that is the most visible and directly influential source for changes in the game. The committee makes most of the recommendations that are voted on by owners — recommendations that are the culmination of a process, not the extent of it.
'You look and you say, ‘Well, the [Competition] Committee is all powerful.’ Not true. The committee is really a conduit for the game. What is good about the committee is the opportunity to sit in a room and vet ideas over and over again.”
— Rich McKay, Competition Committee Chairman
In a 2013 interview with 'NFL Total Access'
In the process that it directs and leads, the committee listens to owners, receives recommendations from its Coaches Subcommittee and Player Safety Committee, surveys teams for feedback and suggestions, meets with the players’ union, consults with officials and heeds advice from outside medical experts and the league’s senior vice president of health and safety policy. League experts review injuries, analyze statistics, dissect trends and scrutinize videos of plays and playing situations.
“It’s not just nine people pushing this forward,” said Atlanta Falcons President and CEO Rich McKay, who has been a Competition Committee member for more than 20 years and its chairman since 2011.
Even after a rule is implemented or modified, the committee’s work isn’t done. The NFL reviews a new rule’s impact using statistics, video and input from teams, players and medical advisers to make sure it is having the desired effect.
When the NFL is unsure about a change, it uses the preseason as a testing ground. Instant replay — an essential aspect of the game for most of the past three decades — was initially tested in the 1978 preseason. More recently, in the first two weeks of the 2014 preseason, the NFL tested moving the line of scrimmage for extra-point attempts to the 15-yard line from the 2-yard line to make the success of those attempts less predictable.
For Every Change, A Reason
The impetus for a rules change can come from almost anywhere — controversies over plays or players, unusual circumstances and trends in scoring, injuries and penalties. That’s been true from the league’s earliest days. Its first playoff game in 1932 — a game forced indoors by deep snow and frigid temperatures — inspired one of the most significant rules changes in NFL history.
In that game, Chicago Bears fullback and future Hall of Famer Bronko Nagurski faked a plunge, stepped back, jumped and completed a lob pass to Red Grange for a key touchdown in his team’s 9-0 victory over the Portsmouth (Ohio) Spartans. The Spartans complained bitterly that the play violated a rule stating passes must be thrown from at least 5 yards behind the line of scrimmage.
The controversy contributed to the NFL’s 1933 decision to allow passes from anywhere behind the line — a rules change that legendary Bears owner-coach George Halas said he proposed. That change provided a big lift to the passing attack, which boosted scoring and differentiated NFL play from the college game.
The Game Changers
Cfl Vs Nfl Rules
Like with the 1932 game, certain games in NFL history stand out for their impact on the rules of the game. Iconic and controversial plays like “The Holy Roller” or “The Immaculate Reception” have forever changed the way the game is played today.
The Immaculate Reception
At the time of this 1972 AFC playoff game between Pittsburgh and Oakland, a consecutive double-touch of a forward pass by the offense was illegal,
but officials ruled that an Oakland defender tipped the pass before Pittsburgh’s Franco Harris caught the ball. His shoestring catch won the game in the closing seconds in a play later dubbed “The Immaculate Reception.” This play was a jumping-off point for further exploration of the rule, but it didn’t cause an immediate change: Double-touch forward passes didn’t become legal until 1978.
The 'Isaac Curtis Rules'
When the NFL changed its rules in 1974 to restrict defenders’ downfield contact with receivers, some people referred to them as the 'Isaac Curtis rules.”
That’s because, in a 1973 playoff game, the Miami Dolphins roughed up Curtis, star rookie receiver for the Cincinnati Bengals, and limited him to one catch for 9 yards in Miami’s 34-16 victory. Paul Brown, the Bengals’ founder and head coach, was an influential member of the Competition Committee. “When we played the Dolphins in Miami last year, they cut Curtis down consistently,” Brown was quoted saying after the league approved the rules change in 1974. “I don’t think he ever got 5 yards downfield. But this rule wasn’t put in just for him. It was put in to make the game exciting.”
The Holy Roller
Oakland won a 1978 game against San Diego as time expired
when quarterback Ken Stabler fumbled the ball forward and two other Raiders intentionally threw or batted it forward until one of them could fall on it in the end zone for a touchdown. After this play — famously named “The Holy Roller” — the NFL approved a new rule: If an offensive player fumbles on fourth down or on any down after the two-minute warning, only the fumbling player can recover and advance the ball for the offense.
The 'Lester Hayes Rule'
Stickum was a popular adhesive that receivers and defensive backs applied to their hands to help them catch the ball.
Oakland defensive back Lester Hayes took the use of Stickum to another level, applying it nearly everywhere on his uniform as well as his hands. The substance contributed to his stellar performance, including 13 interceptions in the Raiders’ 1980 championship run. That was a bridge too far for the NFL, which in 1981 banned the sticky stuff.
The Crown of the Helmet
Competition Committee member John Mara said this 2012 play — in which Cleveland’s Trent Richardson knocked the helmet off Philadelphia’s Kurt Coleman
— helped convince him in 2013 to support a rule that prohibits a runner or tackler from initiating forcible contact with the helmet’s crown, unless it occurs in the area of the field between the offensive tackles. The committee had discussed this type of rule for three years and reviewed every play from two weeks of the 2012 season to determine how often (11 times) the penalty would have applied.
The NaVorro Bowman
Fumble RecoveryIn the January 2014 NFC championship game, officials awarded possession to Seattle, even though replays clearly showed San Francisco’s NaVorro Bowman gaining possession first.
At the time, the NFL only allowed replay reviews of fumble recoveries at the sideline or end zone, citing the difficulty in determining possession in a pileup, even with replay. This play convinced the league that it should change the rule and allow replay reviews of loose-ball recoveries anywhere on the field.
That’s Entertainment
As the rules changes after the 1932 playoff game show, the NFL has championed changes that promote more scoring and more exciting plays.
In the 1930s, leaders of the still-young league wanted to make the professional game more entertaining in the hopes that its popularity would surpass that of college football. By 1940, the NFL had legalized passing from any point behind the line of scrimmage, removed penalties for multiple incomplete passes in the same series of downs, moved hash marks closer to the center of the field and instituted a 15-yard penalty for roughing the passer. It even adjusted the shape of the ball to make it more pass-friendly.
“If someone wants to accuse the National Football League of promoting offense to make the game more exciting, [the committee] believes the league should plead guilty.”
— From a 2012 Competition Committee report
“Offensive/Defensive Balance: An Historical Perspective”
In a 1940 report, the Rules Committee stated bluntly: “Each game should provide a maximum of entertainment insofar as it can be controlled by the rules and officials.” The entertainment value of the game, it added, could be measured by “the number of plays per game of a type that will be pleasing to the audience.”
NFL consultant and statistical guru Hugh “Shorty” Ray — enshrined in the Hall of Fame for his contributions to officiating and rule-making — reinforced this notion.
During his work for the NFL from the late 1930s to early 1950s, Ray crunched the numbers and found a direct correlation between scoring and higher attendance — a statistical basis for his recommendations of offense-boosting rules changes. His devotion to statistics as a way to analyze and improve the game also stuck with the league.
Unintended Consequences and Outside Pressures
Flash forward to 1972. In that year, the NFL moved hash marks to their present-day location: 70 feet, 9 inches (about 23.5 yards) from the sidelines, exactly in line with the goal posts. The league wanted to boost offenses by widening the short side of the field, where defenses used the sideline as an extra defender.
It was a natural solution for the league; in the game's initial decades, the use and movement of the hash marks had been critical for adding excitement to the game.
Evolution of the Hash Mark
In its earliest years,
the NFL field — like the college one — did not contain hash marks.
Unless someone ran out of bounds, the offense would start its play wherever the ball was declared dead on the previous play — even if the ball clung to the sideline. The offense often used the next play to get a better field position — or avoided running plays that could place offensive players near the sideline.
In 1928,
hash marks made their first appearance, according to playing field diagrams.
Presumably, they were placed there to assist with the rule in both college and professional football to spot the ball 15 yards in from the sideline when a ball carrier went out of bounds.
In 1933,
college football rule-makers, noting statistics showing 14 downs a game were wasted by offenses trying to move into a better position on the field,
decided the ball would be moved to the hash mark for any dead ball between the mark and sideline or out-of-bounds play. They also moved the hash mark to 10 yards from the sidelines. Two weeks after colleges approved the change, the NFL voted to do the same.
In 1935,
independently of college football authorities, the NFL moved the hash marks to 15 yards in, further opening up the pro game.
In 1945,
the NFL moved the hash marks again, this time to 20 yards in.
The closer to the center the marks got, the less reluctant offenses became to design plays toward the sidelines, increasing their play-calling options and excitement for fans.
In 1972,
the NFL moved the hash marks to their present-day location: 70 feet, 9 inches (about 23.5 yards)
from the sidelines, exactly in line with the goal posts. The league wanted to boost the offense, which defenses stifled by stacking defenders on the wide side of the field and using the sideline as a 12th defender on the short side by forcing the runner out of bounds.
The 1972 change did help the running game — the number of 1,000-yard runners doubled that year, from five to 10, and rushing yards per game climbed. But the overall impact on the offense was not what the NFL intended or desired.
Field goals became easier because the ball now could be placed and kicked from a hash mark aligned with the goal post — a better angle for kickers than the previous location. That placement also meant that teams didn’t have to waste an offensive play trying to move closer to the center of the field for kick attempts.
The shift also hindered the passing game by making it more difficult for quarterbacks to get a pre-snap read on defensive coverage and call an audible to change the play. Because it didn’t have to protect an especially wide side, the defense no longer had to reveal its coverage by committing players to a side before the snap. This enabled coaches to better disguise the coverage and stifle passing attacks.
The hash marks’ new location also helped pass defenses by creating visual markers on the field for the five underneath zones some teams liked to play at the time. In 1972 and 1973, passing yards per game declined.
The announcement in 1973 that a rival professional league — the World Football League — would play its first games the next year put pressure on the NFL, said Pro Football Hall of Fame historian Joe Horrigan. The upstart league sought to attract fans with rules that were friendlier to the offense than the NFL’s.
In 1974, the NFL implemented a package of changes to reinvigorate the game by boosting the passing attack, increasing the opportunity for big plays on kickoff and punt returns, reducing the incentive to kick field goals and minimizing drive-stalling penalties. Some of these proposals had been considered individually for years, but were finally approved as a package “to put the emphasis on scoring touchdowns instead of winning by kicking field goals,” Paul Brown, a Competition Committee member, told Sports Illustrated at the time.
The changes included:
- Moving the goal posts from the goal line to the end line, immediately making every kick 10 yards longer and getting the post out of the way of pass patterns in the end zone.
- Making all field goals missed beyond the 20-yard line result in the other team's taking possession at the line of scrimmage.
- Moving kickoffs from the 40-yard line to the 35-yard line.
- Prohibiting the offensive team on punts from moving downfield until the ball is kicked.
- Reducing penalties on offensive players from 15 yards to 10 for holding, illegal use of hands and tripping. In the interview with Sports Illustrated, Brown cited NFL statistics showing the rarity of an offense recovering from a 15-yard penalty.
- Allowing a receiver to be chucked only once by a given defender after the receiver has gone 3 yards downfield.
The World Football League disbanded midway through its 1975 season.
In 1978, the NFL further freed up receivers with the illegal contact rule, restricting contact beyond 5 yards downfield. And it loosened the interpretations of holding by offensive linemen by giving them permission to extend their arms and open their hands on pass plays. This had the desired effect of opening up the passing game and reducing conservative play calling.
More changes were made in 1994, due largely to statistical trends showing a 22 percent decline in touchdowns and a 14 percent increase in field goals in the previous decade. At the time, half of the league’s teams were averaging fewer than two touchdowns per game.
Striking a Balance
Cfl Rules Vs Nfl Rules
Even though some fans think that rules changes always favor the offense, it’s not true. Many restrictions affect blocking techniques and other offensive tactics. As was noted in a 2012 Competition Committee report, the 1978 illegal contact rule “simply restored the traditional relationship between the receiver and the defender.”
Defenders ran with receivers without contact until the 1960s, when they began using the “bump and run” technique to move receivers off their routes. That technique took advantage of an anomaly in the offensive and defensive pass interference rules: A nonblocking receiver couldn’t initiate contact with the defender from the time the ball was snapped, but the defender could initiate contact anytime before the pass was thrown.
With the illegal contact rule, beyond 5 yards downfield “the defender has the same obligation to avoid contact with the receiver as the receiver has to avoid contact with the defender,” the committee said. “We have never viewed that as favoring the offense.”
Protecting Players,
Preserving the Game
The committee also favored defenses by placing limitations on the chop block — part of its ongoing mission to protect players from injury as much as possible while keeping the game fair, competitive and exciting.
In a chop block, an offensive lineman blocks a defensive lineman high while another offensive player comes in and blocks him low. Offenses used the technique effectively, especially for running plays, but it resulted in knee injuries for defensive linemen.
From 1979 to 1996, the league placed increasingly stricter restrictions on when and who could use the chop block. In 1981, it essentially eliminated the technique for pass plays; in 1996, the NFL made it illegal for all running-play blocks “away from the flow of play” if the two blockers were not lined up next to each other.
That didn’t bring an end to the debate over the chop block; you can still find arguments for and against these restrictions and many other game rules.
Improving and Preserving the Greatest Game
The history and evolution of NFL rules changes is, at its core, a story about the league’s willingness to make any change it believes will benefit the game, its players or its fans as long as it also preserves the game’s integrity. Whether for fairness, safety or entertainment, the NFL remains open to change.
The position of the goal posts on the field illustrates the NFL’s balancing act.
In 1933 the NFL wanted to make field goals easier to reduce the number of tie games, so it moved goal posts from the back of the end zone to the goal line. It worked: The number of field goals doubled, and ties, which occurred in roughly 20 percent of all games played in 1932, dropped to less than 5 percent of games in 1933.
Nearly 40 years later, circumstances had changed: Kickers were now more specialized and field goals had become too easy. By 1973, the three-pointers accounted for nearly a quarter of all scoring. In 1974, the NFL responded by returning the goal posts to the back of the end zone.
Kickers, however, have become so proficient that the long-term impact has been minimal. Whether it’s because of better talent, technique, training or field conditions, more indoor stadiums or other factors, today’s NFL kickers convert field goal attempts in record numbers — more than 86 percent in 2013 — even from longer distances. Field goals regularly account for more than 20 percent of all scoring in a season.
Is there anything the NFL could or should do? How would the game change if the league narrowed the goal posts or moved the hash marks so they don’t line up with the goal posts? Would the game be better off, or worse?
As with every other rules change in its history, the NFL must carefully weigh all of those factors and more before making a change. It’s what the league must do — for the good of the game.
The sport may be most commonly known as “American football,” but football is becoming more and more popular in other parts of the world, too. In fact, football has plenty of roots in rugby. While we think of football as an American sport, rugby was actually introduced in Canada for the first time in North America back in the 1870s.
The National Football League (NFL) is the most well-known league in the world, but the game has also gained a massive following in America’s neighbor to the north. In fact, the Canadian Football League (CFL) has been around since 1958. The nine-team league is divided into two divisions, a four-team East Division and a five-team West Division.
While both the CFL and NFL are obviously football leagues, the two do not share all of the same rules. So, what are the differences between the NFL and CFL?
Length of Schedule
The NFL season consists of a four-game preseason, a 16-game regular season, and the playoffs. The CFL season is actually longer. Each of the nine teams in the top division of Canadian football play a 21-week regular season, with each team playing 18 games in that span.
While NFL teams play 16 games over the course of 17 weeks, each CFL team actually gets three bye weeks. The NFL season runs from late summer into early winter, while the CFL gets underway typically in mid-June. The Canadian season usually comes to a close in late-November, which is when the NFL is in the midst of its regular season.
As is the case in the NFL, CFL teams begin preseason camps about a month before the start of the regular season. However, the CFL’s preseason spans just two games compared to the aforementioned four-game NFL preseason.
Alignment and Playoff Seeding
Scheduling isn’t the only difference between the NFL and CFL. As mentioned, the CFL has just nine teams, with two divisions split unevenly. The NFL is much bigger. The top American football league has a whopping 32 teams divided into eight divisions, featuring four franchises apiece. The NFL is also split evenly into two conferences, the American Football Conference (AFC) and National Football Conference (NFC).
Each CFL team plays two games against each of the other eight teams during the regular season in addition to two divisional games with rotating opponents each season. In the NFL, every team plays all three of their division rivals twice during the regular season in addition to a number of other non-divisional games.
All four teams in the NFC East will play each other twice per season. Then, all four teams may be scheduled to face each of the four teams in the AFC South.
Every NFL division champion earns an automatic berth in the playoffs, and there are also a pair of Wild Card teams in each conference that will qualify. As a result, you are not required to win your division in order to qualify for the NFL postseason. If a team still has one of the top two records among non-division winners, that team will get in.
The top two seeds in each conference get an automatic bye through the first round of the NFL playoffs, and home field advantage is determined through regular season record. The No. 1 seeds in either conference will have home-field advantage as long as they remain alive in the playoffs.
In the CFL, the top team in each division gets an automatic berth in the division final. That means they get a bye week for the division semifinal, which features the second-place team in a division hosting the third-place team. However, if a fourth-place team in one division finishes with a better record than the third-place team in the other division, the fourth-place team will qualify.
Because of the massive discrepancy in the number of teams in each league, the NFL playoffs feature four rounds, while the CFL playoffs feature just three. The NFL’s championship game is called the Super Bowl, while the CFL teams play for the Grey Cup. The Grey Cup is the second-oldest trophy in North American professional sports, just behind the National Hockey League’s Stanley Cup.
Both the NFL and CFL use a single-elimination format in postseason play.
Rule Differences
The number of teams, scheduling, and playoff formatting aren’t the only differences between the two leagues. The rules of the game are also quite unique to each football league.
The field of play is 110 yards long in the Canadian league compared to the 100-yard field utilized by its American counterpart.
The Canadian end zones span 20 yards, while the NFL’s end zones are 10 yards long. The goal posts in the NFL are situated beyond the out-of-bounds line at the back of the end zones, while they are at the front of the CFL end zones. CFL teams kick their extra points from the 5-yard line, while the NFL recently moved their extra-point kicks back to the 15-yard line.
NFL teams put 11 players on the field at a time, while CFL teams have 12 men on the field. The extra offensive player in the CFL is usually a player in the backfield, while the extra defensive player can line up anywhere on the field.
The NFL gives a team four downs in order to gain 10 yards, while there are just three downs in the CFL. As a result, the CFL game tends to be more pass-happy, as short-yardage runs tend to be less effective when you have just three chances to get to the 10-yard marker.
Cfl Vs Nfl Rules
One of the biggest discrepancies is the ability of offensive players to move prior to the snap. In the NFL, just one offensive player is allowed to move along the line of scrimmage prior to the snap, and every player has to be stationary at the time the ball is snapped. In the CFL, any backs and receivers may move prior to the snap, and receivers may even run toward the line of scrimmage in order to gain a running start, if they so choose.
Fumbles out of bounds are also adjudicated differently. In the NFL, the team that most recently had possession will keep the ball if it is fumbled out of bounds. In the CFL, though, the team that touched the ball last prior to the ball bouncing out of play will get possession.
Both leagues use the standard touchdowns and field goals for scoring, but a “rouge” is a scoring option in the CFL that the NFL does not have.
The kicking team will earn a single point if a kickoff or punt goes out through the end zone or if the receiving team declines to return the ball from the end zone. However, no points are awarded for missed field goals that happen to bounce out of play.
There is also no “fair catch” rule on kicks or punts in the CFL. Instead of that rule, the CFL rules say that no defender on the kicking team may come to within 5 yards of a kicked ball until a player on the return team has touched it.
In the NFL, kicks may only be attempted from behind the line of scrimmage, whereas in the CFL any player on the field may kick the ball at any time. There is plenty of strategy involved in this, which is a drastic difference between the two leagues.
Conclusion
While teams in the NFL and the CFL are technically playing the same game, there are clearly vast differences between the leagues. The differences in rules and the differing schedules make each league unique from a betting perspective. The lengthier regular season gives CFL bettors more opportunities, but the fact that there are just nine teams means there are plenty of repeat matchups, especially compared to the 32-team NFL.
Knowing the differences between the leagues is obviously hugely important from a betting perspective. So, taking time to learn the basics now will pay off in the long run for your CFL or NFL betting endeavors.
