Well, I think the path is clear(ish) for Wisconsin - win out and hope a few others lose. I just don't see a way for the Big-10 to get a team into the mix other than Wisconsin, unless some weird things play out among those first 8 teams. There are just too many teams for OSU or PSU to pass to get there without a bunch of unexpected losses.
One of Georgia or Alabama will lose for sure, but if they win out in the regular season and play a close game in the SEC championship game then it's still quite possible that both get in.
Notre Dame is everyone's darling and has played a tough schedule. They get in if they win out, but they still have a couple of tough games coming. Lose one big and they are probably gone. Lose close to Miami and they might still be in the hunt, especially if Miami wins the ACC.
Clemson goes if they win out. Miami goes if they win out. The ACC will take care of itself unless, again, one of them loses an unexpected game or Miami loses big to Notre Dame. If Miami loses a close game to Notre Dame and beats Clemson I think they go.
TCU or Oklahoma could get in if one of the above falters, but they might both be done if they split their likely 2 more meetings.
I think Wisconsin gets in if they win out, but only if multiple teams of those above lose an unexpected game. The path is even harder for OSU and PSU. The Big-10 could get shut out, especially if Wisconsin loses in the championship game.
