Any time you have media saturation of an athlete (or any person, for that matter), you are going to have people who idolize them and people who hate them. I don't really have an explanation for why that happens, but it's pretty much a law of nature. It's somewhat easier to explain in sports because if the media darling plays for a team you like, you'll love them. If they play for a rival team, you are going to hate them. I don't like Tebow because he is the QB for a team that beat one of my favorite teams last season (Alabama in the SEC Champ. game). That being said, I was rooting for him in the UK game because I hate UK more than I hate Tebow or Florida.
I kinda like Tom Brady, indifferent towards Eli, but absolutely hate Peyton Manning. Peyton was part of a Tennessee Vols team that came to Louisville and committed one of the most classless acts I have ever seen in a college game. They ran through the U of L band when they took the field when the band wasn't really in their way. It was retarded. It doesn't help that he plays for my Titans divisional rival, and I've heard that off the football field, he is a complete moron.
BTW, I don't think you are stirring controversy by suggesting a college football playoff system. Damn near everybody except those that profit from the bowl system agree that a playoff system is needed.
