you take a slow footed xtra large man like mckinnie, and ask him to play in a zone scheme designed for quick athletic lineman. he's gonna look like crap.
also, mckinnie got a wake up call. went from 6-7 mill a year to ? vet minimum?
All that said. I'm still glad he's gone guy frustrated the hell out of me. always seemed to be standing there watching the tackle. Vikes are now forced to draft a new left tackle next year.
