Now this would be an interesting match up!!
Winners of U.S.A.'s SuperBowl vs Canada's Grey Cup. Initially 2 games. One in a U.S. city with NFL rules & regs, 100 yds, 4 downs. The other in a Canadian city, with Canuck rules & regs, 110 yds, 3 downs, and all the back bacon you can eat. If necessary, the rubber would be determined by the point spread, and where it would be played.
Have my people call your people and we'll set it up.
