Personally from what I could see on TV, (I was on the injured list this week (Back)), I thought it was a mild improvement. I am not sure how this group will do against Big Ten Defenses.
My biggest concern is pass protection there was one guard (I couldn't tell who, but I thought it was Kne) who continuously was allowing penetration into our backfield, and Sims (who I thought would be a strength) also struggled at a few points in the game. When you get bigger and faster athletes up against this line a lot of those Hurries may turn into sacks. Zwick especially is not CK when it comes to moving your feet, and avoiding the rush.
The running game was helped by the passing game. The O-line was effective more than it was dominant, which agains CUSA competition worries me. The only player I thought looked good all game long was Mangold. I could have missed it, but I didn't notice him getting beat or knocked back all game.
They did take care of their assigments well and picked up the blitz well which I really did like that.
The screens and sweeps did not work as well as I hoped today.
I would give the oline a C+ because it is the first game. If we see a similar performance next week it will be a C- to D+
