I have seen quite a few teams run at him and it has worked. Not saying he can't play the run but nowhere near as well as he rushes the pass. He's not very good in coverage either from what Ive seen. Point Blank: He's no Demarcus Ware or Clay Matthews
The Spinal Stenosis could be a big deal down the road as well..
He still goes top 5 prob., top 10 at worst
