Biography: Posted 25/4/3 as a senior after moving into the starting lineup. Junior totals included nine tackles with one tackle for loss.

Positives: "Explosive one-gap tackle who makes a lot of athletic plays on the field. Gets leverage on opponents, works his hands well and quickly changes direction. Flashes the ability to chase the action laterally, is explosive in all his movements, and rarely gets knocked off his feet. Effective with his hands and shows good punch with the ability to knock blockers aside."

Negatives: Lacks bulk and can be neutralized by a single blocker. Marginal pass rusher and wasn?t very productive in college.

Analysis: Donaldson has shown flashes of skill the past two seasons and improved as a senior. He's a penetrating defensive tackle who could be a reserve in a one-gap system.

Projection: FA
