Marquez was the first name that popped in my mind seeing this thread. It is actually pretty insane how he can go down and just get up like nothing happened. Heck even using his opponant wildness trying to finish him off against them. Maidana is also a animal, both in the Khan and Morales fight i thought he was on the brink of getting KO'd but about 2 seconds later he looks like nothing happened to him.
Morales was gonna be the first name I put forward but the TS said `knocked down` & my boy Morales was never floored in his prime so I left him out of this one.... if your talking best at recovering after simply being hit by a knockout type punch regardless of whether you go down or not then Morales is the man, one of the quickest to recover in all boxing history (see the left hook Barrera nails him on the jaw with in the last 10 seconds of round 7 in their first fight for proof :scaredas
