Absolute nonsense. The guy is 5'10 with narrow shoulders and is more often than not outweighed by his opponent on fight night.
This! Maybe Lomanchecko can finish his career at 135lbs. But his greedy promoter wants him to hurry up the process. They all have to grow into them naturally not forced. And also Spence seems to be able to do SMW eventually when he gets older.
I think that with one or two tune ups at 154 that Spence would beat Canelo. Actually....I take that back....Canelo would duck him so in that case Spense could not beat him.
Crawford currently comes in the ring at 160 already 13lbs over the WW limit while Lomachenko was 137 against Martinez and was 132/134 in recent fights right at the 135 limit in the ring. Your natural weight rational is a bit off.
