The only scenario I see the B12 getting 2 teams in is if 1 goes undefeated and another finishes with 1 loss. No 2 loss team is getting in from the B12. 3 loss teams from both the SEC/B1G will get in before a 2 loss B12 team.
It’s highly likely we see 4 SEC teams and 4 B1G teams get in. That leaves 4 spots with 3 of the spots going to conference champs from B12/ACC and highest ranked G5 champ. 1 spot left is more likely to go to Notre Dame or a 2nd ACC team than the B12.
