The defense won and controlled the game. Period, end of story. The offense stalled and looked pretty bad at times, especially the run game. A couple of scoring drives only required the offense to get 20 yards. So yes, I agree with the OP. Based on defense and field position, it could have been a blow out by half.
Time will tell. Perhaps USU is very good on defense but I don't think so.
The mind set may be "how can you complain about a 31 point win," but I'd say the OP is more in line with the coaches opinion of the game. I hope to goodness they are looking at some of the play calling and execution from Sunday, because the defense will not be able to cover up that many offensive mistakes against better teams. If you punt the ball eight times in a game, you cannot claim offensive success.
There was basically no pressure on then offense to score. In two weeks these things that seem like a scratch will be a gushing wound.
Worley didn't hurt the team but he missed badly on several deep balls and at other times never found the open receiver. They were basically relegated to dink and dunk.
The running game is the biggest concern. No other thing to say than it was unproductive.
Someone posted about comparative recruiting class ranking between the two. There was more talent in one UT recruiting class than a USU will have in a decade. If it weren't for the abysmal last five years no one would have given this game a 2nd thought.
