re: If LSU and Tennessee both win out...

I think a lot of chaos needs to happen for LSU to make the playoffs. 1 loss Georgia is likely in, 1 loss big 10 champ is in. Undefeated TCU is in.
1 loss Tennessee is likely in if Georgia wins SEC, but may need Utah to win the pac 12.
Oregon is likely in in if they win out and Georgia wins the SEC.
LSU is in if they win out, TCU Loses the big 12, Illinois wins out beating Michigan in the big 10 championship, and Utah beats Oregon, possibly might need Clemson to keep looking like the worst P5 conference champ.
