That is exactly what they will try to do - put more people in the box than you can block. The problem - Alabama's current running game attacks the edge, so putting people in the box doesn't help with that. Also, the RB becomes an additional blocker when the QB keeps the ball.I do expect them to sell out to the run and they've got a few more bodies than UT at this juncture. They really want to create 3rd and long then let their two DEs go to town. I think 1st down passing off the play action would not be a bad idea.
If they load the box, you will attack the edges. If they spread out, you will attack the middle in the run and pass game. Only if they can stop both of those things does Hurts have to win the game with his arm. They haven't been able to stop any of those things this year against less capable offenses. I like your chances.
