He's doing a lot of shooting in these. On those moves where he's instantly in the backfield you're seeing something drawn up for him. He's got one move here and that's the swim. There are a couple of things you can glean from those, though. First, look at that handspeed. It's amazing, violent, and fluid. Best of the potential picks in this regard. Second, watch how devastating that initial club is. Specifically the play where he shot the a gap against Ohio State when they had him at the 1-tech. He jumped that snap like a sumbeech, but look how off balance that club got the center. Even if he had a chance to slide (which he didn't) that club would have flat stoned it. Powerful hand technique and FAST.
Pass rush is an easy eval, he's decent enough. His agility is insane, too.
Here's the fun part of the applicapable eval. Unless he gets a great jump on the outside, he engages the o-lineman and either goes for the bull or looks for the ball to clog a lane. Nice awareness, yes, but when he engages the tackle watch his initial contact. This is as close as you're going to find for 2-gap comparison. Most bull rushers churn their legs and work their hands to drive the blocker up and back. (Matthews, Clay) Think your standard engage and lockout sled drill. Watt doesn't do this. He engages the player instead and works from there. When he takes the player note how his punch stands a 300+ pound man straight up. No wildman crazy bullrush, just a punch that is devastating. You need that to 2-gap well. Nobody this year has that punch.
That early Ohio State clip where he got washed was a nice read by the back keying the backside end (Watt). Flow away zone and Watt drives for the common backside cutback lane as it looked like an outside zone (at least to me) He actually had position on the tackle and was playing it pretty well. The back made a great read on the backside end (Watt), made a hell of a cut and made his tackle's job really easy. Stuff like that explains the washing knocks you frequently read. The truth is out there, albeit a tad more nuanced.
