Most Americans dont realize that the CFL has a lengthy and storied history. The league itself has been around since 1930, and the Canadian Football championship"known as the Grey Cup"has been contended since 1909. 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.

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 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'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.

Of all the rule differences between the NFL and CFL the one that has the most significance on the game isnt enforced on the field; its enforced in the GMs office. Canadians are big on laws and rules to protect their national identity"thats why their TV and radio stations are required to devote a certain percentage of their airplay to Canadian content. That has led to a number of Canadian-only media stars both good (The Tragically Hip, Sloan) and bad (Avril Lavigne, early 90s white rapper Snow). The CFL has a similar rule which requires that 19 of the 40 players on a roster must be Canadian born. This keeps the CFL from becoming a de facto NFL developmental league, and helps maintain its unique identity.

Perhaps the greatest misunderstanding is that the average NFL fan looks at the rules of the Canadian game with more players, a wider field, and fewer downs and concludes that the game is a wide open shootout similar to Arena Football. Thats not really the case"youll see some offensive battles but most games end up with final score totals in the mid to high 40s. In Arena Football, youll frequently see teams with potent offenses enforcing their will over and over again against teams with porous defenses. You dont see that too often in the CFL. The rules may be different, but as is the case in American pro football you need a solid rushing game and a stout defense to win games and championships.

There's also more parity in the CFL than even the NFL, which is famous for the competitive equality of their teams. The reason is fairly simple--football at the high school and college level in Canada simply isn't as competitive as in the US. That means the mandated ratio of native players also serves to facilitate parity within the CFL.

Among the 'non-Canadians' on the team, its also important to note that the CFL doesn't get the highest level US college players. Most with NFL ability are in the NFL, or on a NFL team's practice or developmental squad. There's definitely some American players that are uniquely suited to the CFL game, but the general level of talent is similar to that seen in the Arena Football League.

The bottom line is that despite the rule differences and personal quotas the CFL game is still football and can be enjoyed the same way. Once you understand the unique attributes of the Canadian game youll start to enjoy it almost as much as the NFL.

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.
