I've been listening the past years about some schools wanting a playoff, and some teams not wanting a playoff. Its obvious that the teams that play in tough conferences want a playoff, and the teams that play in weak conferences don't. I put together a list of conferences that would be pro-playoff and anti-playoffs.
Big 12 (Texas,ou,Kansas,Missouri,Colorado)
Big East (West Virginia,Louisville,Rutgers)
Big 10 (Ohio State,Michigan,Wisconsin)
ACC (Miami,Virginia Tech)
The TV ratings have steadily dropped since the 2005 national championship game (last/only time BCS got it right). I'm pretty sure the country is sick of watching USC beat down over-rated Big 10 teams in the Rose Bowl every year. USC actually had a pretty bad year this past year(for them), and still won the Pac-10. Ohio State wasted everyone's time by trying to play in the national championship game the past two years. Notre Dame wins 9 games and almost automatically wastes a BCS game spot.
The BCS screwed it up again this year, and an SEC school brought the playoff topic up again. Ohio State immediately said they wouldn't agree with a playoff system, because they have a good relationship with the Rose Bowl. I think Ohio State realizes they wouldn't have played in the national championship game this past year if a playoff system was in place, and probably won't in the near future.
On a good note though, USC and Ohio State play this year(should eliminate one).
