I can’t see the committee taking a Tua-less Alabama over a one loss PAC 12 champion and a one loss Big 12 champion. If so, then I’ll have lost all faith in college football.
Alabama is finished, period. Even if they win @ Auburn and finish 11-1, the value of that Auburn win won't overcome the value of Oregon's win over Utah, or Utah's win over Oregon.
If you're Oregon or Utah, you root hard for LSU to beat Georgia, (because a UGA win possibly gets both Georgia and LSU into the playoff) and you root for Ohio State to beat Penn State and Minnesota.
But Alabama is done.
