Positives: Passes the eye test -- impressive frame, thick lower half and overall length with 34-inch arms and 10 1/4-inch hands. Has the athleticism and foot quickness to do the job in a short area. Has added 30 pounds of bulk at Nebraska. Improved fundamentals. Very good toughness.

Negatives: Limited the past three seasons by injuries (ankle, back) and wasn't an every-down player in 2011. Carries sloppy weight and isn't an elite athlete. Poor balance with a bad habit of lunging, bending at the waist and spending too much time on the ground. Not overly physical. Raw and has missed significant playing time.
