I can hardly imagine Jones at light middleweight (156 lbs) when he fought at the olympics, fighting himself up to 193 lbs against Ruiz. I mean, he still looked quite muscular at that weight
Am I right in thinking Castillo was once a Super-featherweight? Also Khan was pretty big for a lightweight
Not so much muscular big but Prince Arron who won tonights Prizefighter Light Middleweight title is 6ft 3. Looked huge for the weight although he struggled to make it by all accounts
Urango is extremely top heavy. His legs are like twigs which allow him to fit that massive frame into 140 lbs. Gamboa is very muscular, but he's pretty small at just over 5'5 and was the smaller man against Jose Rojas(not just in height but overall). While his skill will probably allow him to move up in weight class without too much problem, I think he'd be pretty small at Super-Featherweight and tiny at Lightweight.
yeah, guzman was quite big for superfeather and lightweight already but this guy is even much bigger and also taller.
