You have to have an offense to go up against them. How often has Utah had that, especially since they started playing UA?
For one, like I said, stop with the Rod vs Sitake stuff. It's stupid to single him out. It's Rod vs basically everyone. He almost always puts up points. It has nothing to do with Sitake.
So that being said, that he's going to score, one of the ways to slow that down and simultaneously keep up or go ahead, is to have offense of your own. No offense means you're just continually giving the ball right back to the hands of his offense. You want to keep his defenses on the field, not his offense.
Utah the last 3 years against them:
Last year to end the game, the last quarter and a half Utah went punt, punt, fumble, punt to make them lose a closer one.
2014 was just Utah punting all game.
2013 for the 2nd quarter alone went Pick 6, punt, INT, punt, missed FG, punt.
Of course they're going to score when they've always got the freakin ball. They've got a good offense and you have to have some of your own in order for the ball to not always be in their hands.
