Chavez is the greatest, that goes without saying.... BUT Sanchez might very well have been the BEST, I won`t argue with that too much, Chavez was the greatest tho if we are being fair, Sanchez died at 23, he likely would have been the greatest but as it is, Chavez is Mexico`s greatest.
I wouldn't be shocked if Nelson beat Sanchez in a series fight somewhere, sometime, but all things considered I would bet on Sal every time. The less Nelson presses in a rematch, the less likely he is to win. That sounds contrary to popular belief, as Sanchez wanted opponents to come at him, but Nelson wasn't a sage enough pure boxer yet at that point to trouble Sanchez with that tactic.
