He was / is a tweener with almost dt size but not quite. And he was underwhelming in basically all tests at the combine. 10 reps 5+ second 40 etc. he played a style of pass rush in college that wasn’t projectable as a pro, speed rushing off the edge.
He’s shown to be far smarter and adaptable than expected, guys like that are always valuable. A lot of positions are chess games with the opposition, he’s good at finding ways to win battles and playing with in his tool set. His hand rush and bull rush are good enough to play the edge, and hes a guy who plays faster than he runs. Hes just a damn good football player, not a track athlete type.
