FWIW, I would rather we play a 5 or 6 loss Cal team than a low loss CUSA or Sunbelt team.
Years from now when we look back on our bowl record, is anyone going to care that we beat Cal-Berkeley, who barely qualified for a bowl game?
What they (or we) are going to remember is that we beat a team from the PAC-12 in a post season bowl game.
It's about reinforcing our reputation, recruiting and the optics associated with beating a P-5 team. On the flip side, losing to a P-5 team is a little more palatable than losing to CUSA.
