While football in the United States is associated with crisp autumn days and cool nights, in Canada professional football begins in the summer time. While NFL training camps won’t open until mid-summer by then the Canadian Football League (CFL) will be well into their regular season schedule.

The CFL is almost as old as the NFL, coming into existence in’30. The league’s Grey Cup championship trophy is even older, having been awarded to the best Canadian professional football team since’09. There have been a number of NFL stars who got their start in the CFL including Doug Flutie, Randall Cunningham and Jeff Garcia.

While the CFL plays football at the highest professional level of competition outside of the NFL, there are a few differences in the game:

First of all, the football itself is bigger–the CFL ball is larger than its American counterpart. If you know anything about rugby, its roughly the same as a #3 rugby ball meaning it is somewhat longer and fatter than the NFL ball. The CFL field is also longer (110 yards) and wider (65 yards vs. the NFLs 53.5 yards), and the CFL end zones are 20 yards deep as opposed to 10 yards in the NFL. The CFL goal posts are on the goal line, while the NFLs are on the end line at the back of the endzone.

CFL teams are allowed an extra offensive player (a wide receiver), and on defense they’re allowed an extra defensive back. This means that 12 players can be on the field at one time as opposed to 11 in the NFL. CFL football also differs in that teams only have three downs to gain ten yards, as opposed to four in US football. The phrase “two and out” is as commonplace in CFL football as is “three and out” in the US game.

There’s also a significant difference in the way the game is scored. The first time many US fans see a CFL score update reflecting a 1-0 game they’re usually left scratching their head in confusion. CFL teams are able to score a single point, known as a “single” for a kick that lands in the end zone such as a punt or missed field goal.

The rule differences don’t end there–CFL teams are required to maintain a certain percentage of Canadian born players on their roster. The idea is that this will protect the unique identity of the game, as well as prevent it from becoming little more than a farm system for the NFL. Currently’ of the 40 players on a CFL roster must be Canadian natives.

Many US football fans look at the rules that include more players, a wider field, and fewer downs meant to encourage more passing and expect to see a wide open high scoring style of play similar to Arena Football. That’s not really how it works out–most games end up with final score totals in the 40′s, but the game itself really isn’t much more offensively oriented than its American counterpart. The rules may be different, but as in the NFL you need a solid rushing game and a stout defense to win games and championships.

The requirement of native born players making up 50% of a CFL roster also results in a much more even distribution of talent across the league. Certainly there are good teams and bad teams, but the end result is greater parity than is found in the NFL.

The CFL isn’t in a financial position to draw the top level US players away from the NFL or, in most cases, even a NFL practice or developmental squad. While some US players are uniquely suited to the CFL style of play, most of the US players that end up there are of a similar talent level as to that seen in Arena Football.

Despite the differences between the CFL and American football, at the end of the day its still high level, professional football. Once you understand the unique aspects of the CFL, it’ll become second nature much as NFL viewers quickly assimilate rule changes there.

Before the Internet became ubiquitous, it wasn’t easy for an American fan to keep up with the CFL. While they still don’t receive coverage on ESPN, the Internet affords access to the sports media of every CFL city along with the national Canadian sports media at sites like Slam! Sports. The CFL’s official site is also a great source of news, stats and information on Canadian football.
