This is all a moot point if BYU loses, but just for fun:

#2 Ohio State may lose to Indiana but I wouldn't bet on it. In fact, I'd be surprised if OSU doesn't win this by 2 TDs +.
#3 Texas could possibly lose at Texas A&M but that complicates things maybe even more for BYU if the Aggies jump BYU.
#4 Penn State might have a chance to lose at Minnesota but I won't count on that.
#5 Indiana at Ohio State.
#7 Miami at Boston College could be a close one but BC hasn't been playing as well lately so I wouldn't predict this.
#10 Ole Miss at Florida this week. Florida has been up and down; maybe they have one more surprise left in them?
#11 Tennessee at Vanderbilt. It could happen but this one is another longshot.
#13 SMU at Virginia, and vs. Tulane both could be close games but I'd still pick the Mustangs to win both.

Not a lot of opportunity to move up with losses from other teams. BYU just needs to win at ASU this week, take care of business against Houston at home the following week, and show up big in the title game. I won't be too shocked if Colorado loses to Kansas this week and play themselves out of the title game.
