As this point after seeing pretty much a lot of teams on tv, I would put Cincinnati at #1. They have been impressive but they should go to the national championship if they win out including the win over WVU and Pittsburgh(who has been a surprise this year).
Florida has been struggling for the last few games. Alabama had a brief scare against Tennessee(they will be a monster in a year or two under Kiffin). None of the top teams looked particularly impressive which tells me that it's a pretty weak year up on the top compared to the past.
