Gregy Hardy is virtually identical to Brock Lesnar in size. Brock posted much better overall combine results than he did, and Brock is a B+ level athlete. Actually I take what I said back, Greg Hardy is a B- level athlete and probably needs at least 24 months training to become UFC champion. It makes sense Dana wants to keep him out of UFC for now.
