ESPN.com evaluation: DE Mathias Kiwanuka
After the injury, he did not seem to play with the same aggressiveness displayed earlier in his career. Kiwanuka possesses outstanding athletic ability and speed for his frame, and his production at the collegiate level was exceptional. He is a tall DE prospect with great size potential, but there is some concern regarding his inability to add extra bulk and to hold up at the point of attack against the run.In order to maximize his physical skills in the NFL, Kiwanuka will need to get bigger and stronger, while also improving his overall technique. In order to maximize his draft status, Kiwanuka must play with good leverage and show the ability to hold his ground against top offensive linemen during this week's practices and game at the Senior Bowl.
