The combination of physical stature, power, explosiveness, and then putting it together with top notch metrics during albeit limited playing time (sat behind Ray Lawry last year and shared time with Kesean Strong this year)...should make him draftable at worst.
He caught 44 balls the last two years so he's been involved in the passing game. The elusiveness metric ranks #6 out of 61 backs. His missed tackles per rush is #5 of 61.
I think at worse you're getting a Jonas Gray that hasn't wrecked his knee heading into the NFL. At this point in time Gray was in rehab. Apparently, looking at that pro day footage, Jeremy Cox is in peak physical condition.
