Edit: This is the second fight where Sharkey was stopped. Sharkey was still the defending champion here and he was winning the fight before he was stopped. I could only find footage of rounds 4,5,6. I only watched one. Round 4 stats at 3:30. 3:58- Sharkey jabs and then feints a right hand. He puts all his weight on his front leg when he feints and both his hands are next to his body. He's wide open for almost everything. 4:05- Carnera lands a jab. He follows up with a left hook. Sharkey brings his lead foot back first since his weight was on his rear leg. Even though Carnera doesn't land the left hook, Sharkey falls off-balance because he brought his feet too close. 4:10- Sharkey throws a jab to the chest. Right side of his face is exposed since his right hand is at his waist. And he's leaning forward when he throws the jab when you're supposed to lean to the side so you're a narrow target (harder to counter). 4:11- He follows the jab with a left hook. He starts off well by getting low and turning his body to the left to get leverage but his left hook was terrible. His right foot gets ahead of his left as he throws the left hook. He starts off orthodox and ends up southpaw after the left hook. The fundamental way is to throw a left hook with a forward shuffle. You push off your back foot and close distance while maintaining your fundamental stance. 4:29- Sharkey feints a jab. He transfers all his weight to his lead leg again and he's leaning forward. If Carnera were to throw a jab or counter with his right, there isn't much Sharkey could've done defensively. 4:31- He makes the same mistake 2 seconds later. First, he steps forward with his lead leg and puts all his weight on his lead leg. Then he throws a jab and tries to cover distance by leaning forward. Ends up losing his balance and stumbling forward. 4:32- As Sharkey falls forward, Carnera throws a left hook. Sharkey ducks under the hook but then he leans back with his hands down to avoid the right hand and loses his balance again. 4:34- Sharkey literally walks into a jab. He walks into Carnera's range with his hands down and no head movement. 4:35- After eating a jab, Sharkey throws his own jab but leans forward to reach Carnera once again and loses his balance, crosses his feet. His feet were too close when he threw the jab. He did step in with his jab but he stepped too far out for him to maintain his balance. 4:43- Sharkey throws a jab but leans forward far too much and almost falls over, again. 5:00- Sharkey walks into a jab again. He takes a big step forward with his hands down and Carnera throws a jab because Sharkey is right in front of him and he lands. Sharkey throws his own jab with all his weight on his front leg, leaning forward. Carnera parries the jab and Sharkey loses his balance again. He was overextending way too much, his right foot almost came off the canvas when he threw his jab. 5:11- Sharkey is leaning to his side (crouch). Carnera lunges forward and Sharkey sees him coming and pulls back his lead foot first putting all his weight on his rear leg. Ends up staying in the same spot as Carnera throws his punches. If he had stepped back with his rear foot first, he'd be out of danger. You move one foot at a time, when Sharkey is bringing his front foot back, his rear foot is planted to the ground. And by doing so, his feet end up close to each other which is a pretty basic fundamental error. 5:18- Sharkey jabs to the body with his head at centreline, eats a Carnera jab. 5:20- Sharkey throws a 1-2. Overextends when he throws the right hand and falls off balance and eats a jab. He threw a right hand from orthodox stance. When he was done throwing the right hand, his right was foot was ahead of his left. 5:28: Sharkey jabs and leans forward again putting his weight on his front leg. He keeps his balance here. 5:30- Sharkey throws a jab to the body and then leans back with his hands down to avoid the right hand. The right hand lands. 5:40- Walks into another jab with his hands down. If he tried to move his head, tried to parry or counter-jab and still got hit, it wouldn't be bad at all. It's just that he's a stationary target here without any form of defence. 5:41- Sharkey throws a terrible left hook. I've never seen an orthodox fighter throw a left hook and turn southpaw at the same time. That was terrible technique. 5:44- Sharkey throws a jab with his weight on his lead leg again, leans over too much and falls off balance. 5:54- Another one. Jabs from too far out but leans over to compensate, loses balance, feet cross, misses the jab. 5:55- Again, he gets jabbed in the face. He's standing right in front of Carnera with his hands down. He doesn't parry and he doesn't move his head at all. 5:42- Terrible footwork. He literally walks backward to get away from Carnera. 5:45- Leans forward too much as he jabs. That's a rookie error right there. Leaning forward to cover distance. You lose balance, can't follow up, and you're vulnerable to counters. Sharkey threw a jab leaning forward 7 times in just one round. A fighter like Carnera is too slow to make Sharkey pay for his mistakes.
