This.
The secondary has been the weakest part of the defense for years. That may still be true, but I don't consider them weak this season. Cal and ASU are explosive teams, offensively, and our secondary has been up to the task. USC has a lot of individual talent, but they don't seem particularly cohesive, the importance of which cannot be overstated. I figure the last couple of weeks, and all the drama, will either galvanize them, or break their will. Either way, if Utah's defense is ready, this game is ours to win.
We are in the driver's seat in the south. If we keep winning (I believe we are past the real meat of the schedule), we have total control. Doesn't matter what anyone else does.
