Size helps cause you can take a punch better, you can punch harder, you are stronger and have more strength in the clinch
Chin does not improve with weight. That has been refuted on here already. Punching power depends upon technique. Pacquiao hit harder at the lighter weights then at welterweight.
Chin improves when you build your neck,core and leg muscles thus obviously adding some weight. Also when you learned technique your punching power is obviously gonna be greater if you build your base strength and add some muscles
Amir Khan would not have a better chin if he put on weight. Jack Dempsey, Joe Louis, and Marciano definitely hit harder than any super heavyweight in boxing.
You don't think, that the 195 lbs version of Jimmy Ellis took a better shot and punched harder than the middleveight version?
If punching power and punch resistance doesn't improve then why did Manny bang the weight on???? He was an in and out fighter, seldom wrestling or in clinches.
Upon what do you base that statement? For 1, Prescott would not have sparked out the Khan who fought Canelo. Peterson would not have bullied the Khan that fought Canelo. If Lennox Lewis fought every opponent Marciano did, he would have been more dominant and destructive. I have no basis to that statement but I am wholly confident that Lewis hits harder than Marciano.
I wonder why they have weight classes at all. The way some people view the sport here I'm surprised there isn't a call for one open weight championship and obviously the most skilled man will win because size doesn't change anything.
Size does change things. Artificial weight changes things. only the tallest guys can carry the most artificial weight. It's got to the point where the inferior boxer wins because he can carry more artificial weight. It impedes the shorter guy because it's harder to overcome reach disadvantage once a fighter is too heavy. Artificial weight is the never seen before muscle mass that takes fighters outside weight to height charts. BMI, US army weight requirements that champions usually used to meet. Once everything that aided speed has been taken away from the sport, smaller HW guys they needed to put weight on to compete. Since the biggest guys carry the most they have the advantage. HW us another sport now. It's become the behemoths SHW division.
thats rediculous to say because Ellis out grew the MW division the extra weight improved his actual punch resistance! why cant it be the anticipation level required at the slower weight class prevented him from taking the kinds of punches he could not react to in time as a MW? it the punches that you dont see that knock you out. a former MW will see more punches coming his way as a HW. surley thats more Logical than eating yourself to a stronger chin?
Behemoths? Tyson had no issues beating Golota or other big men. Spinks had no issues beating Cooney. Dempsey had no issues beating Firpo or Willard. Louis had no issues beating Carnera or Baer. Cunningham heavily dropped the last lineal champion. Huck went life and death with the number 2 ranked HW today. Haye is probably a favourite over anyone not named Wlad. Adamek was a highly ranked HW for years as was James Toney. These men can be beaten by those skilled enough. On recent threads people have picked Walcott to beat Ortiz, Charles to beat Tua and Moore to beat Briggs. Lewis wasn't great because he was big. He was great because he was the most skilled HW on the planet.
Obviously Ellis had better punch resistance at HW than MW. quite clearly that is the case. It isn't advisable to give away so much weight and allow such an advantage over you. Moore could outbox Briggs but he certainly isn't doing it weighing 175 or 160 pounds. Give him time to build muscle and weigh in at 205 pounds and he'd be strong enough to do the job.
Punch resistance generally does not seem to increase with added body weight. A fighter with a weak chin can pack on loads of weight and still has that weak chin.
all that is clear is Ellis got knocked out less as a heavyweight. there is a logical and illogical answer to why that might be. it's obvious to people who fully understand boxing that it is impossible to eat your way to a harder chin. its a lazy myth to subscribe to. just think about what you are saying. having the weight to stand your ground is an entirely different matter. presenting a larger physical obstacle offers less vulnerability but not entirely in a punch resistance sense.
