JMO, but I think that Alabama should play to your strengths to build a lead, then focus on the run game. You had better get this figured out before November, and you won't get it figured out if you just keep playing to your strength.
Saban said that he is just taking what the defense gives him. We all get that. But Auburn, LSU and Clemson are not going to give him ANYTHING. They are going to disguise coverages, and the number of men in the box pre-snap will be different than the number of men who remain in the box post-snap. You are going to have to line up and beat them. If you don't have the running game sorted out by then, they will blitz Tua on every snap and try to take out the one player who can beat them.
