two things are equally apparent;
1) the NFL is an American only sport, it is not a world sport, and it's kinda weird to crown the winers 'WORLD' Champions
2) the Superbowl should absolutely NOT be hosted anywhere outside of USA (maybe TOR one day if TOR establishes a franchise, but i digress). The appeal to fans in Europe is the NFL product 'as is'...it would lose much of its appeal if it were de-Americanized.
Superbowl is great as it is...leave it the heck alone
