1. Clemson is likely already out of the title game.
2. If ACC champ game is Miami and one-loss SMU (given it was to BYU), they are likely both in. SMU losses would be to BYU and possibly Miami in the champ game.
3. Big 12 is another story. BYU, assuming regular season undefeated, is in even if they lose in champ game. That is worst case scenario for ND since that would result in 2 Big 12 teams in.
4. You can pretty much assume the committee is going to bend over backwards to get 3 SEC and 3 BIG teams in. It is going to be very interesting if Indiana and PSU end up with one loss. Watch out if Indiana beats OSU (not that it is likely) since OSU would have to lose 2 more games to be knocked out.
I know too many people look at the current rankings and assume they will play a bigger part than they will. We have already seen both Indiana and BYU jump ND in the ratings. Watch how quickly SMU will move up now that folks will pay attention to them since they control their own destiny to the ACC title game.
ND is clearly on the bubble and needs to look impressive in all of our games. Home playoff game chances are slim.
