Sheffield was a productive, three-year starter in college. He has a good combination of size and strength for the position with average athleticism. He is a tough competitive defender but lacks explosiveness on contact. Leverages the ball well versus the run but doesn't have the same instincts and reactions versus the pass. He lacks great edge quickness when rushing the passer but has enough variety with his moves and counters to be effective. He is a solid wrap-up tackler in confined areas but lacks great lateral agility and quickness in space to be reliable. Sheffield is a bit of a 'tweener and may not have enough overall skills to push for a starting position at the next level.

Big kid with a large frame. Quick in the short area and takes proper pursuit angles. Strong athlete who maintains good balance and is difficult to move out of running lanes. Solid tackler who wraps up the ballcarrier. Very productive and durable in college.

Does not possess the speed to be a sideline-to-sideline player. Late reacting to play action and takes too long to locate the ball. Struggles dropping into coverage and lacks the athleticism to stick in man coverage. Stiff in the hips and loses speed in transition. Has short arms and lacks an explosive punch.
