Getting Dexter back for Stanford will be a huge help, he's the best RB on the team (I believe, by far.)
The quarterback situation obviously needs to improve, but I'm not so sure it's all on Wimbush or Book...It starts with pass protection. I like the way Wimbush makes the most out of broken plays, but those broken plays are coming almost every other play because, I think, the offensive line needs to improve a lot. We know they're big and athletic, but they still need to learn and improve quickly. Not sure if it's experience, the new coach, or a lack of talent compared to last year's guys, but if they can somehow shore up the O-Line, it's going to help the passing game, no matter who is back there throwing the ball. While I don't think the offense will get to that "championship level" we pine for, I do think they'll get better and start to make more big plays in the passing game and put up more points.
With Stanford and VT looming, however, I fear there might not be enough time to make significant strides without taking a loss (or two).
