If we beat ND, we will be about #9. We will jump UGA, OSU, and A&M. We should jump Lousiville, eventually, just by principle. That would leave 2 SEC, 2 PAC-12, 2 ACC, and tOSU. If think Clemson beats FSU, but three things are certain in life- death, taxes, and Clemosn choking a game they have no business choking. Remember who the DC is! If we play well, we will pass tOSU, but I think they lose one that they shouldn't. That would leave passing the Oregon/Stanford winner, and we would need a loss by either. Outside of 'Bama, I don't think any of those other teams goes undefeated. Oregon has the best shot, but the PAC-12 has some potholes in it. I know it is early to look at the polls, but projecting this can be interesting.
Polls are highly unlikely to be an issue for OU to play for a title. OU not being an elite squad might get in the way though.
