The closest thing we've seen to a "blueprint" for Floyd recently came from, of all people, Zab, and in typical Zab fashion, it only worked for 4 rounds. But I agree completely that we can dismiss the "crowd him, hit his arms, pressure him" idea that worked fairly well for Castillo. I don't think Floyd's defensive game is much different, or his offensive arsenal, but he is leaps and bounds beyond where he was at lightweight, physically and mentally. This is why although Cotto - Mayweather has to happen, and should happen, I can't see Cotto winning, and almost have a hard time seeing him be competitve. Floyd is going to counter him all night walking in, and is probably strong enough now to hold his own on the inside. But if for no other reason than history, the fight must happen. Deep down, even Floyd knows that calling yourself the best welterweight ever, and highlighting that resume with a semi-reired jr. middlweight and three natural 140 lbs. champions (one with a foot in the grave), doesn't add up. And anyone who wants to criticize him afterward by saying Cotto fought at 140 also is just an idiot. Cotto is so much stronger and complete at 147, I'd just about say this should have been his natural division all along.
DLH was extremely close to winning that fight. He had a very impressive defense and was blocking a ton of shots. Unfortunately PBF also had a good defense... That was the layout for the fight, a defensive fight, with neither being very aggressive. It was anticlimatic considering all the build up and hype. There was no way that it could live up to the hype generated.
SRR was a welterweight, then later on he moved up to MW and eventually fought at LHW. But i do think he is bigger than Floyd, just look at the weight classes he was able to compete in which Floyd's frame wouldnt hold well. But a good comparison could be made for both at WW, considering SRR would be naturally a bit bigger, but not really that much because if he were, then he wouldnt be fighting at WW. ps: you could also consider SRL naturally bigger than Floyd, just look at the weight clases they started off, and where they finished.
