I agree with the notion that the defense was set to stop the run, and passing was the logical response. I don't think Saban was looking to send a message to Trent, or that he was even thinking about a 100-yard streak. When coaches start thinking about things like that, they lose focus over just winning the game.
From a balance standpoint, we are averaging 229.25 on the ground and 228.38 through the air. Uncanny.
