As of now, based on the season so far, I think:
B1G: Champ+2(Oregon, OSU, PSU)
ACC: Champ+1(Clemson, Miami)
B12: Champ+0(who cares?)
Non-P4: (Boise?)
Notre Dame: ?
That leaves 4-6 spots depending on non-p4 and Notre Dame. I think the SEC gets Champ+3(or more) if we're ranking the best teams in the country. If record plays too much of a part, Champ+2, but that leaves 1-3 spots, and who is playing better competition who deserves it more?
