No one in the top 10 unfortunately, best to put him against the LHWs or CWs unless you account for a few years of allowing him to take PEDs. Even then i dont know if he would rank top 3 I really do think he benefitted off of catching the end of the Dempsey era (still lost to him btw) and being before the beginning of the Louis era. Sharkey was never astounding tbh
He'd be a cruiserweight of course, and would be the best cruiserweight in the division, assuming you allow him to camp up he'd be a favourite for me to beat everyone but Usyk.
He was clever enough to potentially beat anybody, including Usyk. Obviously he was not the most consistent operator, and that would be reflected in is results now as then.
