Fighters that lost their hype that u still have hope for

There were lots of fighters being touted as the next big thing in the sport for a while that have failed their tests due to a flaw that continues to get exploited and has yet to be corrected Victor Ortiz had all the tools to be the next big thing, but failed miserably due to his lack of heart and skill, and recurring in-ring stupidity Amir Khan has what it takes to be the next big thing, but he has a weak chin, and lacks the proper defensive skills to protect it Then there r guys like Andre Berto, Devon Alexander, James Kirkland, and others who lack a little more than just one key element to a potential ATG career So which one of these fighters, among others not named, do u think still has what it takes to turn their careers around and wind up on top or near the top of the boxing world?
