Spence is a weight bully with less skill than Tommy had at 147, however Hearns proved himself above 147, could Spence have been as impressive against the same opposition, I know Spence would be destroyed at 175 but what about the fighters Hearns fought at154-168, what percentage of these bigger fighters could Spence have beat, era for era in fantasy fights?
Hearns wasn't fighting Hagler and Leonard every time out, Spence would outbox the scrubs that he kept busy with. Spence doesn't have the power to go above MW though I don't think, unless he changes his whole style and benefits from not cutting down to 147 in ways that are hard to predict.
tommy was a much bigger man, just streamlined. they arent going to jump divisions the same way. and there is no such thing as weight bullying, nothing is free in boxing. only people that dont understand the game use that term.
