The SEC would be lucky to get 2 teams in much less 3.
1) No one left on their schedule is good enough to beat Clemson
2) No one in the Big 10 is going to beat Ohio State.
There is no chance that they ignore two undefeated conference champs so that pretty much eliminates the 3 SEC team narrative.
It is more likely we will see 4 conference champs in because:
3) Georgia isn't going to finish the season with one loss.
4) If the committee is serious about schedules, Alabama doesn't have the schedule to get in especially if they don't get to the SEC title game. Depending on how it plays out both Baylor and Oklahoma will have stronger SOS.
