It was a little difficult coming up with the final rankings. The main problem is that there aren't really 25 teams that I think deserve to be ranked. A lot of teams near the bottom of the top 25 before the bowls lost and a lot of borderline teams lost too. I ended up putting Iowa at #25 because of their two big wins against Michigan State and Missouri. Most of the other bubble teams don't have any quality wins and all have troubling losses (like Iowa's loss to Minnesota).
The rest is pretty self explanatory I think.
