It would never happen, but a 12-0 ND fighting with a 12-0 TCU for the #4 seed could be trouble. Our schedule already kind of took a hit. Stanford was probably supposed to be the 4th toughest game and they looked horrible. They might turn it around, but they looked like a 6-6 or 7-5 team. Texas looked terrible, and I was hoping they'd be our 5th toughest game. they also look like a 6 or 7 win team at best. Pitt already lost their stud RB for the season. Besides Temple/Navy, I don't see anyone on our schedule right now who is going to get to 8 wins besides USC/Clemson/GT.
The Big-12 is so top heavy, TCU could go 12-0 with wins over 11-1 Baylor and 10-2 Oklahoma that look more impressive on paper than anything we'd potentially have. There's never that many undefeated teams to end the year, but I don't think we're a lock at 12-0 with our schedule if a disaster scenario (13-0 OSU, 13-0 Oregon, 12-1 SEC Champ, 12-0 TCU) were to happen.
