Let's make one thing clear right up front: South Alabama is not very good. Nebraska did what they should do with a team like that. The game never was in doubt from the start, and frankly, any criticism can easily be dismissed as nit-picking. On the other hand, not all was great in this game.
Last week, 1-AA Gardner-Webb rushed for 177 yards against South Alabama, so I expected that Nebraska should be able to rush for close to 400 yards. That wasn't in the cards, because Nebraska only rushed 37 times; it's clear that Mike Riley and Danny Langsdorf prefer to throw the ball.
