So over the next few weeks before the conference title games the following top ten teams will filter out.
SEC
At this point I see Bama and LSU among one of the survivors, maybe both while Fl, UGA, and Auburn fall out.
Big Ten
tOSU, Wisconsin are among the survivors with Penn State, and Michigan dropping out. Probably tOSU makes it through.
Big 12
Think Oklahoma has a clear path to the top four.
ACC
Clemson has a clear shot to the final four.
So the way I see it is
All likely in are Clemson, tOSU, and Oklahoma, leaving one spot open, the winner of LSU and Bama. And unfortunately unlike last year ND resume is not good so if one of the big five conference leaders lose I think the loser between Bama and LSU makes it in over the PAC 12 winner or ND.
