They didn't on a couple drives where USC shut them down when their defense needed a break.....
And they didn't when they had the ball on that final drive.
There was a very obvious hole RIGHT UP THE MIDDLE against USC in that game. Why they didn't run the ball up the middle every other play is a mystery to me. USC didn't have a prayer at stopping it, yet Pat Hill continually went back to the pass and Pinegar isn't that type of QB yet.
And they didn't when they had the ball on that final drive.
I guess we have a different definition of "exploit". Evidently you believe a team has to score every time they have the ball in order to "exploit" their opponent's defensive weaknesses. By that definition even the Indianapolis Colts don't often "exploit" defenses. They have to punt every once in a while, too.
I'll stand by my statement that if you score 42 points, you have "exploited" an opponent's defensive weaknesses and should win. If you don't, it would mean that your defense is getting exploited to an even greater degree. Again, that would indicate a problem with your DEFENSE, not offense.
