I think someone who can feint right hands and follow up with a leaping left hook could hurt Floyd. SRR could do this and follow up that leaping left hook with two more, all fast and powerful. SRR had so many options offensively and if Floyd managed to close down that avenue he could revert to those beautiful right hands to the body that he threw around an opponent's guard taking away Floyd's attention from his own upper right side. Eventually, Floyd would adjust and look to counter with right hands to the head and this is where SRR could once again land left hooks. SRR was also great at jabbing while circling to his left, something that opens up angles for right hands to the body when facing an opponent with his lead should raised plus he could fight on the inside. Floyd's "shoulder roll" style was also a much more common way of fighting back in SRR's day so I think he would be the most accustomed to deal with Floyd's awkardness. Tommy's one of my favourite fighters but unless he knocked him out early I don't think he had the stamina nor variation of punches to keep Floyd from adjusting. As great as he was I always remember him jabbing looking to unload that huge right hand or throwing left hooks to the body then head which is fine from the outside but what happens when FLoyd weasles his way inside? But Tommy had that killer instinct and if he was in the same situation Mosley found himself he would've mauled Floyd till he dropped him or the ref stopped the fight. Man Mosley could've done it. It was like watching my clown of a mate on Saturday night somehow managing to get these absolute glamours up to dance with him but he just didn't make a fucking move. Frustrating shit.
