How does Tank handle a puncher like El Chapo in his prime? Rosario back then used to be a monster of LW before the drugs took a toll on him. This would have been an amazing explosive fight and either of them could get stopped. For those who don’t know Rosario he was pretty much arguably the hardest puncher at LW, like a smaller Julian Jackson. He was an all action bruiser who gave Hector Camacho a scare and changed the Macho Man almost completely as a fighter.
