Why I think A&M will win tomorrow.

Saban has consistently had a massive Achilles heel at Bama, spread offenses. When the game is slowed down, and Alabama can just out talent everybody, they win almost every time. When you spread them out, go fast to keep them from rotating personnel, the talent gap becomes less of an issue. Bama's defensive line amazing, but they're also heavy(average of 315 lb) when you go quickly, that advantage can be almost completely negated after a few series. Additionally, makes it more difficult to adjust Defensive play calling.
The biggest reason why I think A&M gets this one, is that while Bama's LB corp is 2nd to none, the secondary is pretty weak. And I would argue that TAMU is just as good if not better at the pure passing game than Ole Miss. The combination of Kyle Allen with those massive Aggie receivers up against that Bama secondary is a mismatch.

A&M will score, and Myles Garrett will get his against Cam Robinson(who has struggled this year). The question is whether Bama's offense will be able to keep up, and I don't have faith in Jake Coker or Derek Henry.

A&M is a match up nightmare for Alabama, because they're a fast paced spread offense with a good quarterback and massive receivers. Which in addition to playing on the road just screams "upset", if you can call it that.
