I was rooting for DeSean Butler and like you said, he was making some nice plays--but once I saw him running back on defense and it seemed like he was sorta dragging that injured leg. He has it wrapped above and below the knee so maybe the bandage support is hampering him a little.
He would be a great comeback story if he can make it back to where he was or even close. That scene in the NCAA playoffs where he's lying on the floor with the WV coach cradling his head to comfort him is indelibly stamped into my memory.
I know they have a high draft pick investment in Joseph, but I'd still bring up Dentmon at this point instead of Joseph.
