Can't argue with Byard's projection. D. Johnson is likely a late pick and Barber must have a excellent pro day (good weight, 40 time, bench) to have a shot. Wouldn't surprise me if someone like Batties grabbed a UDFA contract
TT is going to have trouble. He is undersized for NFL LB and too big be a safety. Doesn't really have the height to play outside in a 3/4. Doesn't have the mass to play inside or outside in a 4/3 IMO. That said the kid has a great motor, is a big hitter and has a nose for the ball. I could see him signing a UFA and being a career special teamer.
I think in the right situation T.T. can be a contributor. the "experts" will say he is too small, but as stated above he has a great motor and and a nose for the ball. They said Ray Lewis was too small and look how his career turned out
TT will need to put on at least 10-15 pounds to play OLB in most 4-3 systems. He would need to put on at least 30-40 pounds to play OLB in a 3-4. However, TT could potentially play one of the ILB spots in the 3-4 which is traditionally undersized (think Wesley Woodyard for Titans)
