As others have said, they are more cohesive offensively than earlier in the season. Wallace manages the game better than Moseley or Frazier and commits fewer back-breaking mental errors, but he lacks the raw ability of either of the former. They've reverted to running more spread/zone read packages and are moving away from some of the pure pro-set stuff they were trying early in the year.
Defensively they are very aggressive and take a lot of risks, but their back-end coverage is horrendous (as has been the case for the entirety of Chizik's tenure) and a physical rushing attack can eventually impose its will against them as they are still not very big on the whole.
Auburn has played better over the last 3-4 games, particularly since inserting Wallace into the starting lineup. But they are still just simply not a good team. They have too many glaring personnel deficiencies at too many crucial spots. They've literally got nothing to lose heading into this game and I'm sure they'll throw everything in their arsenal at us. I'd expect them to try some stuff that they've not really done this season - high tempo, trick plays, lots of spread sets, etc. I think they'll probably attempt to replicate the TAMU game plan, but ultimately their personnel is just not nearly as good as A&M's. Hopefully we'll have our collective heads on straight and put the game out of reach early.
