Utah beat Montana State by 17 points, what exactly do you consider a blowout? Beating someone by 3 scores and leading by at least 3 scores from start to finish is a blowout in my book.
But I said if Jordan Wynn finds his game anyway. If Jordan Wynn still sucks Utah probably won't blow them out.
The point is, Utah looked great everywhere except at QB. And we know Wynn can play, he just has to find his game. USC, on the other hand, was pretty bad in all facets of the game except QB and 1 receiver. They have way more problems that need to be fixed than Utah.
If neither team fixes any problems, Utah probably wins but doesn't blow them out. If Utah fixes their one problem, and USC doesn't fix anything, Utah blows them out. If USC fixes all of their problems and Utah doesn't fix anything (the least likely scenario) then USC probably wins but not a blowout. If Utah fixes their one problem and USC fixes some of their problems but not all of them (the most likely scenario) then depending on what problems USC actually fixes, Utah wins, probably wins comfortably and possibly a blowout.
