Im sure its been stated a million times already, but of course Chop Chop had him a bit stunned, also happens to be the same guy that hurt cotto... much... much worse though. Cotto was actually HURT... i think mayweather was just stunned. If Chop Chop wasnt the worst finisher in the sport this side of Joval... He might actually have wins or at least knockdowns against two of the best in our sport... LOL! .
So lets see. FLoyd gets hurt, takes some steps back into the ropes to get himself together. He gets rocked again and it shows and he steps back into the ropes to recover. Cotto gets rocked, legs get shaky and he goes for hold and within 5 seconds he is dominating the fight again. But Cotto's chin is worse.
every time cotto was hurt it was from a counter punch or a punch he did not see because he was on the attack and gets caught off balance.
