Get-off/Burst - Extremely explosive off the ball and almost immediately gains ground into the opposing backfield. Quickness makes him extremely difficulty to win first contact against. Difficult for guards to square because of how fast he attacks their edge. Carries initial burst off the ball into his third and fourth steps as a rusher. Slips through gaps quickly to play behind the line of scrimmage more than any defensive lineman in the country.
Leverage - Some built-in leverage at 6-foot-2, 6-foot-3, shorter than a lot of offensive lineman. Still plays a little high at times and could benefit from a more consistent pad level, especially when he's tired. Hands are so powerful that when he lands them, his leverage matters a lot less than it will for other defensive linemen. Majority of the time, fires off the ball low and leveraged.
Hand Usage - Ridiculously destructive with his hands usage. Hip tosses, clubs, swims, push-pulls, bull rushes, rips and hump moves are all common on his tape. Devastating power and extremely sudden hands to create movement at the immediate point of contact. Leaves offensive linemen in the dust with one decisive move. Strings combinations together effortlessly as a rusher. Consistently re-sets the line of scrimmage and is almost never controlled by his opponent.
Rush Plan/Counters - Will see some rush plans die out due to high pad level when he misses with his hands early. Has to work to counters more readily, probably the only weakness in his game really worth mentioning. Would benefit a ton from a spin move back inside when a lineman tries to carry him up the arc. Initial rush plan is consistently elite, comes off the ball looking to get up the field and on his opponent's edge as a pass rusher, and has the tools to do both consistently. Rare at college level.
Mental Processing/Block Recognition - Needs to do a better job of identifying zone steps off the snap and knowing when he's about to be reached. When he recognizes that, extremely difficult to reach him. Will often try to backdoor zone schemes which is a lot harder in the NFL. Terrific at IDing vertical blocks and owning the point of attack. Unbelievable anchor to ward off down blocks and even eat up doubles teams. Splits doubles extremely well, doing a good job of getting his shoulders turned so there is no surface area to hit. Good discipline to play a penetrating style but not get so deep he'll allow himself to be trapped either.
Range - Excellent range for the position, has made a lot of plays far outside his jurisdiction due to effort and impressive long speed. Consistently playing in space behind the line of scrimmage allows him to showcase his movement skills really well. Does not have the change-of-direction of an Ed Oliver, but still well above-average fluidity in space.
Bend/Flexibility - Consistently runs the arc around the outside shoulder of the offensive guard, turning a tight path to the quarterback. Ability to finish from a wide angle is impressive.
Tackling - Probably could have had 3-4 sacks in the first round of the playoffs if he broke down in space a little better against Kyler Murray. Has to do a better job of throttling down and not being so aggressive when attacking the quarterback's landmark. When he hits you square, you'll feel it. Great strength to rip runners down outside his frame.
Competitive Toughness - High-effort, high-intensity player with a strong motor. Oklahoma game was the first one I saw all season where he was legit sucking wind in the second half. Sooners pace makes that understandable. Physical competitor on a consistent basis during the season, no plays off.
Athleticism/Size - May not have elite length or testing numbers, but checks the boxes in all areas of size and athleticism, especially when watching him on tape.
BEST TRAIT - Hand Usage
WORST TRAIT - Counter Moves
RED FLAGS - None
One of the easiest evaluations you'll ever see, Quinnen Williams was the most dominant defensive player in all of college football last season, despite being just a redshirt sophomore and a one-year starter. His power, quickness, rush plan and hand usage are all elite, but the scary part is that he still has some room to improve in his counters and in his mental processing. He can play anywhere on the interior defensive line and should be a multi-All Pro player in the NFL.
