Scout.com: NEW 2009 NFL Draft/Combine - Def. Tackles: "4. Sen’Derrick Marks, Auburn 6-1, 290
Positives: Quick enough to be an end, tough enough to play tackle … Ultra-productive. Was the focus of everyone’s blocking scheme … Can really, really move.
Negatives: Might not have a true position. Needs to figure out exactly what he is … Short. Doesn’t have much room to get any bigger"
