How many fights of a prime McCrory have you seen? He wasnt slow. Speed is relative. He certainly didnt have what it took to hang with Curry, but Thurman couldnt shine Curry's shoes. McCrory had much better technical skills than Thurman, and enough power to make him hesitant. Keith wouldn't outbox McCrory, and we know damn well by now that he doesnt have the power to stop top guys. I think McCrory would have outboxed him. Just thinking off the top of my head, I think theres over 20 welterweights in the 80s alone who would have beaten Thurman. I'm not even talking about the HOFmers like Leonard, Hearns, Duran, Benitez, Curry, cause those are mismatches. Im saying that I doubt Thurman beats guys like Colin Jones and Nino Larocca.
I think in the 80s and 90s era of welterweights Thurman is a contender level type of guy who loses to all the best guys. Hearns is not only too much for him, but a lot of welterweights who’d be considered elite.
I've never seen an "elite" guy that was a bad as Thurman. I'd give Khan a chance vs Thurman, never mind that Hearns would fucking kill him.
