Unless Zab is able to miraculously get a new brain...he will never be a force in the sport. I think pretty much everyone can agree that he is physically a very talented fighter...but he is one of the weakest and most unstable minds in the sport. You are guaranteed a mental breakdown from him in nearly any fight. So while i am not a huge fan of Tony, Margarito would dispatch of Zab...as would Cintron. Not that they are more talented fighters than Zab...but Zab just doesn't have the mental discipline to compete on a high level.
