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.

Most Americans dont realize that the CFL has a lengthy and storied history. The league itself has been around since’30, and the Canadian Football championship–known as the Grey Cup–has been contended since’09. More recently, American fans are aware that a number of NFL stars got their start in the CFL including Doug Flutie, Jim Kelly, and Jeff Garcia.

The CFL is a very professional and highly competitive league, but its important to understand some important differences between it and the NFL:

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 to have 12 players on the field at a time, one more than is standard in American football. The extra offensive player is a wide receiver, and on defense they’re allowed an extra defensive back. CFL teams allow a team only three downs to move ten yards as opposed to four in the US game–references to a team going “two and out” are common on CFL broadcasts.

There are also differences in the scoring of the game. The first time I saw a CFL score tied 1-1 at the end of the first quarter I thought I was hallucinating. A major rule difference between the CFL and NFL is the fact that teams can score a single point, which those clever Canadians call a single. Basically, a team is awarded a single point for a missed field goal or a punt that lands in the end zone.

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.

Considering the 21 non- Canadians on the team, its also important to remember that the CFL doesnt get the pick of the litter of American football talent. Certainly those who have the ability are in the NFL, or on an NFL practice or developmental squad. While some players are uniquely suited for the CFL game–former Clemson University QB Nealon Greene, for example, who couldnt make the NFL but has had a lengthy career in Canada–most of the Americans in the CFL are players whose ability just isnt up to NFL levels. Remember Vince McMahon’s failed XFL experiment? That gives a good indication of the type of American player that ends up in Canada.

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.

You wont see CFL news on ESPN, since theyre more interested in featuring spelling bees and lumberjack competitions and letting their personalities like Stuart Scott show how clever they are than covering sports. The good news is that the CFL receives extensive coverage in the Canadian press and all you need to do is visit a couple of websites to stay up to date. Each CFL city has their own sports media, and most have pretty good websites. The best one stop shopping can be found at the leagues own and Slam! Sports, which is roughly the Canadian equivalent of ESPNs website and has extensive CFL news, opinions and statistics.
