If he was trash talking about what Osi has accomplished then I would agree, but McCoy is saying Osi's overrated and soft. When you look back on Osi's injury plagued career then I would agree, Osi isnt a bruiser player he's a finesse pass rusher who isnt know for making any sort of big hit.
The overrated thing can go either way, I personally think Osi is over rated by the media but is still a very good DE.
