'Have to agree with the Corrie Sanders pick. He had the potential to go all the way to the top, and stay there. Instead, he drifted in and out of the picture, never really in top shape physically, never seeming that interested. But he had one of the greatest set of natural gifts of any HW of the last 20 years.....and pretty much pissed it all away.
I think that was more Corrie Sanders's fault than his management's. Corrie never really cared about boxing. He was happier spending time on his game reserve and playing golf. He still got some great pay days for the Klitschko fights when it looked like he was finished years before.
1.) Antonio Margarito had a weak manager- Sergio Diaz that couldnt do much when Shane "EPO-Man" Mosley was "juiced up" with EPO, HGH, when they fought. Then his manager did little or nothing to prevent Margarito from fighting and illegally-loaded gloved Pacquiao in a FIXED FIGHT. 2.) Angulo has a weak manager too.
