I'm holding World Championships in a game I just invented, wanna play?! God Bless America, and me! (Not sarcasm!)
Rest assured the winner of the Super Bowl is the best football team in the world. I do find it amusing that they say world champion, but the fact is, many different organizations say that their champ is the world champ. (15 different boxing organizations, 2 major MMA groups, world cup, cricket...)
But there is no doubt about this, not one country could field a team that can compete with the US in football ( I dare to speculate that a conglomerate of countries couldnt field a team to beat us in football)(short of pirating our players). Youre living in fantasy land if you think that. We invented football and no one else has a prayer of beating us. USA in Turino. woohoo!
And tons of people around the world watch the Super Bowl, not as many as the world cup, but it is a significant number.
