Hagler was the better boxer and brawler. The only advantage Martinez has is speed, and he gets caught by much less accurate and skilled guys than Hagler. Hagler breaks Martinez down and stops him in the mid rounds.
Marvin can win any way he pleased. His best bet is to take the fight in close. Sergio never puts his hands up high enough even if he's on the ropes.
Would Martinez still be called "Sexy Sergio" after this fight? Would it be like the scene in Raging Bull when LaMotta fights Janiro?
