170 seems his JR year. He looks about 190-200. I'd take him if he can grow into OLB in the mound of another Hutchinson or Chisam, small LB, lightly recruited, but can do some good things with speed. Though I wish there were more video of him on run D than just pass rushes.
ESPN is the only one with legit information if they have data under "Testing Results", which they do at their testing combines. ESPN has him listed at 6'0, 190 lb, which might be from last spring (2012).
