Who would win, an NFL team playing by NFL rules, or a Canadian team playing by Canadian rules?

Imagine that you took the best NFL team and had them play an exhibition against the best Canadian league football team.

Normally, of course the NFL team would win easily since they generally have the better players. But imagine that both sides played by their own league's rules. Meaning, for example, that the NFL team would only have 11 players on the field, while the Canadian team would be able to have 12. Similarly, the Canadian rules for motion would apply when on offense, and the endzone for the Canadian offense would be 20 yards deep. Etc etc.

Personally I think the NFL probably still wins, but it might be closer than we'd think.
