PRO DAY RESULTS
Bench press: 20 reps of 225 pounds
STRENGTHS
Massive tackle with very functional length. Looks oafish, but feet are much better than the eye expects. Takes quick steps and good angles for proper positioning to wall off defenders on gap plays. Above-average power in run game and runs legs to create movement. Drive blocker by nature. Block winner at point of attack. Uses well-timed punch and has adequate foot quickness to set out to edge speed. Aggressive, play-finishing demeanor on the field. Plus body control and balance on second-level blocks with ability to sustain. Can brace against power and has feet to counter inside moves in pass pro. Shows ability to mirror and has a wide "success zone."
WEAKNESSES
Stiffness in knees causes him to come out of stance way too tall. Is almost never under the pads of opponent. Too often has to sumo wrestle at impact to get defender centered. Initial lateral quickness not good enough to count on him with back-side cut-offs. Keeps hands too low pre-punch. Unathletic build with zero bubble. Some scouts worry about stiffness becoming an even greater problem after first few years in the league.
