This is purely a guess here, but based on Barney Cotton and his history and the current trends in college football, I think we will be a run first team out of spread formations. This isn't to say we will look like New Mexico and not throw the ball, but I think they will stay a bit more committed to running the ball this season.
Defensively it is hard to say. Based on how they are recruiting so far I think we may be looking at something like a 4-2-5 type set up with 4 down linemen, 2 linebackers and 5 defensive backs. One of those defensive backs will be a 'tweener' type guy that will be sort of a safety/lineback hybrid. I think they are going to try and put as much speed on the field as possible and have guys rally to the ball. (Think TCU style defense)
Again purely a guess.
