We didn't have trouble scoring
I disagree. We scored one TD on four drives in the first half and found ourselves down 31-10 after PSU took the ball in the 2nd half. Our vaunted offense went three-and-out on the first drive, thanks in part to a poor decision on 3rd and short.
Granted, our offense did very well to get us back in the game in the 2nd half. But you simply can't play from behind every game, not with this defense. You literally need to score every drive. You need to start the game with the same urgency that you showed in the 2nd half.
