Moss is most definitely on the lean side but that doesn't bother me. I can see Moss putting on 30 lbs fairly quickly. The thing that really stuck out to me when I watched his film was how well coached he was. Whoever the DC is at Gorman has done a fantastic job teaching these kids. In terms of technique, Moss is light years ahead of most DE/OLB prospects are at that stage. What Moss needs the most is to build his core/functional strength. As a prospect I'm very high on Moss.
As far as Shemar Stewart, kid is a monster. Landing Stewart in addition to Kelly and Moss would be an absolute coup by Mario especially when you consider that if Manny was still here none of them would have given us the time of day. At 6'6" 275, Stewart will make an ideal DE in the 3-4 while Moss and Kelly are most likely OLBs in that 3-4 base but can and will play with their hand on the ground as well when we shift into a 4 man front.
