Strengths

• Tough between-the-tackles defender who shimmies past blockers to fill lanes. Downhill, aggressive run-stuffer with enough strength to stop ballcarriers in the hole.
• He has good reaction skills and awareness. Forceful tackler vs. the run.
• He does not have the elite straight-line speed or quickness, but his strength and pass-rush ability.
• Brings down quarterbacks much bigger than he is. Very good motor and regularly chases down plays from behind.
• Spends a lot of time outside the box in coverage, but he has the strength to hold the edge against large tight ends and linemen.

Weaknesses

• One-speed player, lacking dynamic qualities and doesn't look natural in reverse. Lacks the fluidity to be consistent dropping against the pass with unpolished cover skills.
• Can be too hesitant when he doesn't find the ball immediately.
• High-cut and long-legged, and he does not have elite acceleration.
• Hits up high and misses more tackles than he should.
• Not a sudden or quick-twitch athlete. Will never be the strongest player on the field and can struggle to shed from different angles.
