I watched the first quarter and a half of the Medal of Honor Bowl and he got one pressure and bull rushed a guard right back into the QB on another play. He doesn't look to have the experience to be any sort of early contributor but he certainly has borderline draftable skills. He played 0-tech NT in a 3-4 which I think is great preparation. He's got JJ Watt's athleticism! I don't know why you wouldn't draft him in the 6th or 7th just in case?
Some more comps I've found (Sokoli in brackets)
Greg Hardy
6-4, 281 (6-5, 290)
4.82 (4.84)
21 reps (31 reps)
35" VJ (38")
117" BJ (119")
7.25 3cone (7.19)
Mario Williams
6-7, 295
4.70
35 reps
40.5" VJ
120" BJ7
7.21 3cone
The only other people I can find close to that combination of forty, vert, 3cone and size are Suh, Allen Bailey, Jason Hatcher and Tyson Alualu. There are a couple of prospects: Darrion Scott and Russ Kolodziej who are clearly busts and just miss matching up to Sokoli (Scott has no 3 cone and Kolodziej went sub 35" on the vert).
