We used to have a guy that gave us great scouting info on Nebraska prep athletes, but he hasn't posted in a long time. I did some digging didn't find a lot on Adrrell. I did find this quote from his coach:
He's a heck of a well-rounded player. He started as a sophomore as DE on our state championship team and then moved to LB his junior year. He sees things pretty well and when he catches it, he can run. He's a great blocker — we even told him we were moving him to guard. He played special teams, he blocks, he runs, he catches, he hits. He's very physical and has earned the respect he has.
It will be interesting to see where he ends up. I could see him at LB, or if he adds weight, at DE. The latter might be interesting because, with a former LB at DE, the zone blitz could be very effective. They used to run that when Scott was at DE, but I don't recall them using it much last year. I personally like the zone blitzes better than the all out blitzes.
