Just because someone hits hard does not prove they are god Boxers. If that was the case then Tank would be a world class boxer. In the sherk fight he had a nice reach advantage and was fighting a wrestler. Donít get me wrong I think he does have some skills however I would not list BJ in the top list as MMA boxing skills go.
When you fight a guy with a smaller reach and not very good at boxing you should do well against him.
