Marvin Hagler ring weight

Rehydration existed back then, It was just more uncommon. I'd say 163-165 but thats speculation. Him being about 160 in the ring is more likely.

He'd be a small middleweight now. But Hagler would also be a giant welterweight. The man was ripped to shreads and would definitely be called a weight bully if he cut down to 147. He looked bigger than Castano who is at 154. That could just be his physique though

 

Castano the size of a 140

 

Height of one, but he has significantly more bulk in the upper body and legs than say Josh Taylor, who is big at 140.

He's a pressure fighter so it makes sense. He is also top 2 at 154, should have gotten the decision against Charlo the first time and less skilled and much less durable than Hagler so Hagler being top 1 at 160 nowadays isn't far fetched
