Rumor that Milroe has an injury and might not go against the Ags? If that's true I don't see Alabama winning. Those other two schlubs they rolled out at QB were horribad and almost lost to a G5 team.
Alabama won't be throwing the ball much in either case, so that part doesn't change. The other guys are at least capable of handing the ball off, which I think is the plan either way. The O-line seems to have improved markedly from the first three games (this is not to insinuate that Bama could now beat Texas), in terms of technique, cohesion, and meanness, all of which was lacking at the start of the season. They look pretty devastating when running the ball, so they might be able to grind out an ugly game.
The problem is that Milroe is a big threat to run, and I don't know that the other guys are. So if they lost that, their run game loses a dimension and the Aggie front 7's job becomes simpler. And the Aggies seem to have quite a front 7. They're probably the best equipped to deal with Bama's improved OL out of the remaining opponents.
Definitely gets harder for the Gumps, especially on the road, if Milroe can't go or isn't 100%.
If I had more confidence in the Aggie O-line I'd probably have gone with them in the first place. I don't see Aggie scoring much in this game, but it's possible 20 may do it. Bama has proven they're capable of a dumpster-fire offensive performance on the road. This is probably going to be an ugly game, but one I think either team is going to celebrate if they win, since they probably go on to win the west.
