I'm saying it's better for Arreola to come in at 235-240 than at 254 as a pig.He must cut some weight off.That is not necessarily dehydratation.
I don't think anyone would disagree with that, but you made your comment in reply to my reply so someone asking whether heavyweights rehydrate after the weigh in. I think that's what confused the rest of us. The only reason a fighter needs to 'rehydrate' after a weigh in is if he has dehydrated himself in order to make the weight. That's clearly not applicable to a heavyweight.
I don't think heavyweights would ever put on any significant weight after the weigh in (unless it's Toney + a few burgers), there is quite simply no benefit at all to trying to lose any weight that close to the fight. All the preperation is done in the weeks up to the fight and a HW should be at fight weight on at the weigh in. Dehydration won't have any benefit so expect their weights to be almost the same (plus food minus dumps )
Eric Esch started out around 300 pounds, and as low as 280 for one of his early fights. He fought at 417 1/2 for his last fight. That's a difference of 137 pounds.
I believe Carpentier boxed from Feather??-heavyweight National honours were claimed in many divs. Never a true H/W, he did box Dempsey for the title... stunning Dempsey with a right hand. Common knowledge regarding the bout with Dempsey Langford, clearly the finest to never obtain a world title, also boxed from Feather?? -to H/W.. Jack johnson, may have been another with the same career, rising through the divisions?? Edit.... Just read that Carpentier boxed from Flyweight- to Heavyweight through his career.
Carpentier maxed out about 180 pounds, though he boxed at heavyweight. Back then, at 180 he would only give up about 5-15 pounds to the majority of heavyweights, anyway.
if we base it on weight divisions, pac has gone up through about 11 weight classes since he started his career at 106. that should put him right up there too.
