I think that Carnera fought a tactically sound fight. He kept Sharkey on the end of his jab, and ripped him with the uppercut when he got in close. He took the fight to Sharkey when he opened up a narrow lead, and exploited the openings that Sharkey left when he went wild. Sharkey did not fight smart. He was impatient, and cut corners to compensate for Carneras reach advantage, as we see with those wild rights. When Carnera started to turn the tide of the fight, he became increasingly desperate and careless, and that is why Carnera stopped him. Sharkey was the better fighter, but Carnera was better on the day.
What often goes unremarked is that in 88 fights, Carnera never duplicated that punch before or after.:think
As I have said before, it was not a knockout caused by a single punch that got through. Sharkey was getting stuffed, and was likely already on ***** street before the punch landed.
Morrison by KO. Primo did have some skills, he just didn't have a chin. Not that Morrison was blessed with that either.
Carnera had a pretty good chin. He fought the two hardest punching heavyweights of his era, and was on his feet at the end of both fights. Neither could keep him on the canvas for more than a couple of seconds. He kept going down against Baer because he had a broken ankle.
Well there you go! I always thought it was because he was getting tagged with overhand rights that were thrown with a post card preceding them.
What often get's overlooked is during his training for the Carnera fight the lives of Sharkey's children were threatened.That's a pretty good reason for not putting out your best effort.
