Here's the report of the pro day from NFL.com
Rakim Cox, DE (6-3 3/4, 266) — Cox ran the 40 in 4.93 and 4.94 seconds. He had a 32 1/2-inch vertical and 9-8 broad jump. He did the short shuttle in 4.41 seconds and the three-cone drill in 7.14 seconds. He performed 20 strength lifts on the bench. Cox has 32 5/8-inch arms. He worked out as both a hand-in-the-ground defensive end and in space as a linebacker. Cox will work out at a the regional combine held in Miami later this month.Not bad measurables. He'll almost certainly get some sort of NFL contract, and possibly will even get drafted.
