If the top 3 hold serve, the Big 12 winner should get the 4th spot.
If Georgia wins, I believe LSU is still in. I think the Top 3 could afford a loss and still make it. Clemson is the only one that doesn’t have a great resume, so that would be a good debate with OU if they win the big 12. I don’t think Baylor gets in over any other 1 loss team, OU might.
The Big 12 needs to root for LSU tomorrow. That is their easiest path to the playoff.
