Looking at some other teams ...
If BYU (8-0) can get through the Holy War on 11/9 unscathed, the Cougs close with vs. Kansas, at Arizona State, vs. Houston.
Iowa State-K State is probably for the other spot in the Big 12 title game.
Miami (8-0) closes vs. Duke, at Georgia Tech, vs. Wake, at Syracuse. Honestly, at SU in the season finale might be the toughest game left in that stretch.
Pitt (7-0) has been a great story, but the schedule gets dicey here coming up. SMU and Louisville on the road, Clemson at home.
It's simple for Notre Dame (7-1). Win out against FSU and UVA at home, Army at Yankee Stadium, and USC in L.A, and the Irish are in the playoff. Lose any of those, they're out.
Would an 11-1 Washington State get a sniff? Unlikely, since they're essentially playing a Mountain West schedule and lost by three TDs to Boise State.
