Im not saying what he did was wrong because he won fights so he must have been doing somthing right, what im saying is he could have hit harder in my opinion given the use of good posture, dempsey was a gifted puncher and i think someone less gifted than himself would struggle to pull off the kind of shots he does while still producing powerful punches, some people can hit hard however they hit but for the rest of us we have to rely on propper bio mechanics to deal damaging shots.
