Bad hand use and he keeps his head down. Doesn't matter how fast you are if your head's down. My old DL coach in HS always said "if your head is down, that's where you're going." You can't make the tackle, read the play, or pursue if your head's not up. I feel like this is a common theme for explosive DTs. They come out of their stance almost like a sprinter. Sure, it's great for getting off the ball and into the backfield, but it doesn't help you locate the ball carrier or get off a block. Even Brandon Williams is at times guilty of this.
The other thing is hand use. He still doesn't really have any moves. He could probably develop one hell of a swim move with his athleticism. I'd like to see him work on a speed to power conversion move a la James Harrison. You go quick outside, get the man on skates, and then you turn inside hard for a bull rush. It's tricky to do that on the interior because guards aren't set as deep as tackles, but I've seen it done.
Still, even with this, he's the kind of guy I want out there on 3rd down. He might not get home, but he gets unbelievable push and will force the QB to move.
He needs to learn moves and tracking the ball comes with reps. But when he uses his hands he moves and discards blockers. If he learns to play he will become one of best interior rushers
