Can Utah make the National Championship game?

Yes. In the same way CC Sabathia may return to the Brewers.

Here's what has to happen.
Texas Tech loses.
Texas loses in the Big 12 title game.
Alabama or Florida have to lose once and win the SEC Title Game.
Penn State loses.

And Utah still has to take BYU.

The second and the third ones are the ones that kill Utah's chances.
