We know he's athletic... probably the most athletic heavyweight we have had this millennium. That said, what does that mean for top speed? He could run a ~4.7s 40, but a ~6s 3 cone drill and that would tell us a lot more about position. Those are elite EDGE numbers. If he does that with a 12 rep bench, then he isn't a DE, he's potentially an OLB... but then he would need higher top end speed, so undesirable there.
This is all conjecture, mind you. I don't know any of his stats aside for height/weight, and it is likely that we never will.
