re: Bama has only allowed 4 teams over 100 yards rushing...

I think it is unlikely you're going to stop Auburn. But like another gump poster mentioned, you don't have to.

In theory, hold Auburn to under 200 yards. That is a more reasonable goal. Make Auburn go find 200+ yards in the passing game. That provides the potential for NM mistakes. Moreover, while 400+ yards of offense would probably give AU a strong shot, there is no reason Alabama can't outscore AU in that circumstance.

Now, that is theoretical. In practice, coaches get miffed and make changes that could hurt or help. Saban could get frustrated about our (relative) success on the ground, or Gus could get upset at our (relative) lack of success. Turnovers, special teams, etc., all could mess with this dynamic.

Anyway, the point is that Auburn can have success by your standards, but not by ours. But, as I'll be surprised if we're able to run to our average on you, I'll be surprised if you're able to hold us to your average.
