Name fights where a boxer is getting utterly dominated but bounces back to knock his opponent out. Where he snatches vicotry from the jaws of defeat. Some of my favs: Benn - McClellan Marciano - Walcott 1 (Rocky had been dropped in the first round, and in my opinion was getting outboxed until the thirteenth).
Ward didn't land a SINGLE punch all night. It was like he was in a daze. Merchant was making fun of Ward saying he should be fined for not fighting. Then... BAM. Sanchez is on the canvas crying from a bodyshot. Literal tears.
The ultimate late comeback has to be LaMotta/DauthuileII. Unlike Chavez/TaylorI, this fight had LaMotta needing a knockout in the last 10 seconds of a fight with the classic championship rounds in it.
