Overthinking it.
If the Utes win out chances are very high that enough happened to get them in. There's five conferences, and a one loss champ in the second best one will get the nod. Unless LSU, Clemson, TCU/Baylor, Mich St./OSU all run the table, a one loss Pac-12 champ gets in. And everything in history says that those teams won't all win out.
Let's not act like the Pac-12 is the 2nd best this year.
