Alabama lost to a rival at the end of the season. They blew it, but thankfully so did Wisconsin as if they were in the playoff I think they lose by 20+ last week to any of the other teams in. USC lost more games than Alabama and the PAC-12 as a whole proved weak this year so they didn’t deserve a team that wasn’t 12-0 to get in over a one loss Alabama.
I still think until the team everyone says shouldn’t have been invited, doesn’t advance to the final, the committee picked the right teams.
