That means:

1) Utah has to go 9-0 against : Arizona State, Cal, UCLA, Colorado, NIU, Idaho State, @BYU, @Arizona, @Oregon State. That, in of itself, is a tall order. To not have a single slip up. While Utah has the 8-game streak against us and is 4-1 against both Colorado and UCLA over the last five years, they are 5-5 against the Arizona schools. 

The stars would need to align, and this is probably the easiest domino to tip.

2) 2-1 against: @USC, Washington State, @Washington. To beat one of USC or Washington on the road will be tough. Over the last 5 seasons, Utah is 4-7 against this group, without a single win over Washington State (0 for 3). 

Utah would have to beat 2 of the likely-ranked opponents on its schedule...2 of those games on the road. Hmmmm....

3) Beat Oregon at a neutral site in the PAC 12 championship game. Oregon is tough, and willlikely be even tougher by December. Utah is 2-3 against the Ducks over the last 5 seasons. 

If Utah makes it this far, anything can happen in a championship game. We'll see. 

4) Rank ahead of the B1G AND the B12 champions. Would 12-1 Utah rank ahead of a 12-1 Big Ten champ (Ohio State, Michigan, Wisconsin, Iowa?) or 12-1 Big 12 champ (Oklahoma or Texas?). Doubtful.

So basically EVERYTHING has to fall in Utah's favor, not only to win the PAC 12 South, but also to win the PAC 12 championship game with only a single loss AND to rank ahead of two other P5 champions...when the PAC 12's national perception hasn't been lower in recent memory.

Not going to happen. 

But, I will still be jealous when they play TCU in the Holiday Bowl.
