as I look around this year I just don't see many dominant teams we used to. I think with so many underclassmen going to the NFL that there is more parity in College Football because the top schools are getting hit hard. Just looking the 2010 NFL Underclassmen you got big time programs losing some top underclassmen not to mention their seniors:
Florida 5
Oklahoma 4
USC 3
Alabama 2
Georgia Tech 4
Georgia 2
Iowa 2
Multiple other schools lost some of their best players
A lot of schools on that list have been somewhat lackluster at times this year. I realize that to a certain extent these teams just reload but when you lose so many NFL prospects before they are even Seniors it does seem to have had an effect on quality of play
