This is pure speculation on my part after reading about and watching video of the first practice.
Butch seems to be doing what I heard happened under the Chip Kelly led Ducks. Practices are not only intense but you have to run not walk from station to station, onto and off of the field, plus he wants the team sprinting to their end of the field and off field at the end of quarters and during half times. This stamina level is why many teams playing Oregon cant keep up with them. If the players execute this preparation, we may well give Oregon and everyone else a run for their money and more. I thus christen them the Vol herd.
Raijon Neal seems to be a weight room beast. I saw a little of the following last year but dare say he will be showing even more this season. He will be hard to drag down when tackled. He may well be similar if not as fast as Georgias Gurley and Alabamas Yeldon. In short, what he might lack in speed and I dont buy into his being all that slow, he will make up in breaking tackles and dragging defenders forward.
The only thing that causes me some concern right now is recruiting SEC talent. That Coleman kid may well be a fine pick up, But I hope to see us getting players from our southern states. This is not the ACC, Big East, or MAC. Its the SEC.
