For whatever reason, let's say that gridiron football did not split into American and Canadian variations, but mixed-and-matched parts of both. Here are the differences in comparison to OTL American gridiron football:
Canadian-size football field (110 yards long by 65 yards wide, with two 20-yard end zones with goalposts in the middle of the goal line)
Kicks landing in the end zone (except for successful field goals or if the ball has hit the goal post in flight) are live.
Only one foot needs to be in-bounds for a reception to count.
How would this effect the strategies, types of players who would play at the professional level and the performances of famous football players from OTL (assuming they aren't butterflied away)?
