He looks pretty dominant against sub-par (by NFL standards) athletes ... I wouldn't mind seeing how he'd work out as a FB or a LB—he has that "I'm not afraid to take/make a big hit" mentality, but I'm not sure his "speed" and "athleticism" would be able to beat out NFL guys. That said, lining him up at fullback and telling him to get that one yard on 4th and 1 or having him sneak out of the backfield and catch a pass a few times would most likely end up as a positive play.
I say bring him in! I would love for him to prove me wrong on my highly-uninformed assessment of his talents and the talents of his opponents thus far! He feels like that perfect "Brandon Browner" pick up Pete and Co. is known for, where afterwards you go, "How in the hell did no one else see this guy coming?"
Edit: He definitely has the lateral thing down. If he is free down the sidelines and then as he's about to go down, he pitches to Harvin...boom TD! hehe
