I would like to see how Sharkey would react to that persistent holding behind the head. Probably he would hoist Ali up bare-knuckle style and dump him on his shoulder. Before Ali gets the win via a cuts stoppage he may get one in the groin, as a souvenir.
He was beating the **** out of Dempsey for large parts of their fight. Not a bad fighter at all, in my opinion; just temperamental.
