Its that time of the year again–Americans are getting ready for football. In a few months NFL teams will be opening training camp and college football teams starting practice. Up north, however, the footballs are already flying as pro football is in full swing up in Canada with the Canadian Football League (CFL).

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:

At the most basic level, the football itself is bigger than the NFL ball. It is longer and fatter than the NFL ball. The CFL goal posts are on the goal line, while the NFLs are on the end line at the back of the endzone. 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.

Teams have 12 players on the field at once as opposed to 11 in the NFL. On offense, the extra player is a receiver, on defense a defensive back. And unlike the American game, where teams have 4 downs to move the ball ten yards the CFL has only 3. Maybe the hardest thing to get used to when listening to CFL broadcasts is the frequently references to teams going two and out. There are a few other subtle differences as well”teams only have 1 time out per half, only 20 seconds between plays, and all backfield players can be in motion prior to the snap (as opposed to only one in the NFL).

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.

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–you’ll 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 don’t 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.

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.

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.

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.
