Those are the rare cases
Walking down the street you aren't gonna find a grown man that weighs 140 pounds too often, even the ultra health conscious, weight lifting jogging on the track working out muthafukkers aint weighing that.
Swift is 25 at 140 for 8 years now, he's growing he can't make the weight and I posted picture evidence. Yeah He's a weight cutter he walks around at 170-180 when he's not in camp, but I feel he doesnt do it for an advantage, Swift has been almost damn near begging to go to 147 it's simply evident that he's been's convinced to stay at 140 by a higher power(had 1 more fight post Herrera lined up at 140), when he said he wanted to move up post Khan
I think people think its rare because nobody does it, not because they cant. I can tell you right now that there are several fighters that are 160 plus that will come down as far as they can to fight Floyd. it depends on where the money is. fighters say they cant make weight all the time then come up with an excuse as why they can make it when a paycheck comes calling. Shane said it...swore he couldnt ever make 147 again. some fighters add a disclaimer....saying I cant make such and such bu...bu...bu...I can for a fight with so and so.
Danny may be outgrowing the weight but we have to weight and see. Or like you said, he lives good between fights and cuts weight. Canelo does it. He made 152 for Floyd but cant make 154 for Angulo. Just beware that sometimes its the promoters/managers/advisors that be putting this shyt out there and not the actual fighters themselves.
