Not gifted with one punch power but relentless and intense finishing people off like Alex Steward, Bob Crabtee, Mike White ( actualy the first to have survived but clearly saved by the bell too) and extremelly accurate damaging offensive fighters with power counter punching like when he had that classic WBO vacant HWT title against Bert Cooper.
Not very high. In 29 wins at heavyweight, 17 of them were listed as knockouts. Not a particularly huge ratio for a puncher. In addition, few of his heavyweight Ko's came against truly durable fighters, and many of them were stoppages as opposed to actual knockouts. Had he remained at lightheavyweight, his power would have been an incredible force for years. But as a heavy, I think he's probably about an average hitter.
when watching the cooper fight they were really bigging moorers power up, Its funny how it turned out for him i mean he obviously was very talented as he was heavyweight champ of the world and yet he was soooo insecure and frightend.
