Nice article Josh. I agree what you said. Some of my thoughts:
You failed to mention Jordan Topp on the DL as a factor. I think he may be one of the biggest X factors we have. He's large but agile and can actually play either the DT or DE position although he's obviously going to be DT. He is always around the ball and I hope to see him filling holes this year that we've been unable to do for a while. He's also a threat for sacks at the position and I wouldn't be surprised to see him get 3-5 this year which would likely be huge.
Running game has questions but nonetheless, its going to be better than last year simply because we have a lot more talent at the position along with speed. We did not have that last year and I think by default, that the RB position will be much more productive this year.
Marlin Miller did not average much per catch because most of our passes were the bubble screens and such trying to mimic what Jason Chery was so good at doing and that is making plays after the catch. The problem is that teams are on to what we do and aware that play needs to be used less and you are right, we need to stretch the field a lot more. I'm not sure whether Wolfe is eligible or not for the fall but Lawson and either of the two freshmen will definitely have to emerge to really add that dimension to this passing game this year.
