I actually had time for a ballot this week, but just couldn't pull the trigger.
There isn't too much left to fill a ballot when you take out the teams that are on probation, the teams that are about to be on probation, teams that lost to WAC teams, teams that have RichRod as their head coach, teams that lost to Rich Rod, teams that let a team that lost to RichRod win their conference, teams that lost to I-AA schools, and teams that let a team that lost to a I-AA school win their conference. After nuking all of those teams, I was left with about 15 teams or so before I started getting into 6-6 Big Ten and SEC teams.
FWIW, if I had been able to cough up a ballot this week, I too would've had TCU around #13. Their schedule is crap. It can't be that hard to go undefeated in the regular season against a schedule like that - they've done it twice in a row now. Their toughest test was against a Utah team that got their doors blown off by Notre Dame.
