An Australian, Irish or Brazilian would disagree that football is from the US, they would even disagree among themselves what football is. Even you will probably know that the football that you play has English roots.
Your correct for a change…but we are talking about “American Style” football and not what you mentioned. The only difference is in Canada the field is a different size consider:
FIELD/EQUIPMENT DIFFERENCES:
Field size is an immediate difference between leagues. In the NFL and NCAA, the field is a total of 120 yards long–100 yards of playing field with two end zones, one at either end of the field, each end zone being 10 yards long. The field is 53 1/3 yards wide. NFL goal posts are 18 1/2 feet wide, with the crossbar at 10 feet, while the NCAA widened their goals to 23’4’'. Also, the NCAA uses two supports for goal posts, while the NFL has only one.
In the CFL, the field is a total of 150 yards by 65 yards, having two 20-yard end zones, for 110 yards of playing field.
More differences:
One immediate difference between the other leagues and the CFL is that in Canadian football there are only 3 downs, compared with 4 for the others. The object is still the same; 10 yards must be gained within the downs allotted. Interestingly, there have been petitions to the NCAA to increase from four downs to five, though these have all so far been denied, and any future such change is highly unlikely.
Another area of difference is in team sizes. While college and NFL ball teams have 11 players, the CFL has a twelfth player. Instead of a tight end, the CFL employs two “Slot Backs”. In defense, Canadian teams have an additional linebacker or defensive back, depending upon the play. This is in keeping with Canadian football’s larger field size, where more players are needed to cover the extra space. Arena football, on the other hand, has only eight players. This is possible due to the smaller size of the Arena football field.
Basically my original comment is accurate. NFL is made up of better players of the two leagues and this has allways been so. But some Canadian forum members is can be expected to think otherwise. The same thing has happened with NHL… the power shift to American teams is relentless… Montreal and Calgary are shadows of former glory.
