Subjective rankings need to be supplanted by an objective playoff.
You mean the way all of the other NCAA Football divisions do it?
Back before the BCS days, there was arguing all winter long about who shoulda won the votes, who was jobbed and wound up as #3, but you know what?
No one got hurt by it.
The schools and the bowls still made money, the best players got their shot at pro tryouts, just like now. I was fine with it and I think lots of other fans were, too.
Besides, there is no playoff system I am aware of that will eliminate the real curse of Division I ball - the cupcake games scheduled to pad the W-L record.
