A lot might disagree . But i think it was . shavers never knocked out anyone with a decent chin . The only top fighters he knocked out were norton,ellis and young . Young was a blown up middleweight , ellis was shot and norton was shot and never had a chin to begin with . Shavers reputation of being generally recognised as the hardest puncher in history comes from ali and holmes always blowing up shavers as being a great fighter and great puncher .Shavers knockouts are nearly all against tomato cans. jimmy ellis wasent too impressed by his power . He said shavers didnt hit that hard at all.
