I haven't watched it myself yet, but I hear it's pretty good.link
Its not the full video, but what I saw was good. Its worth it just to see how he moved in his teens and the insane skill disperity between himself and the guys he was fighting. Honestly, if I were on a commision for the Junior Olympics, I never would have let him fight. Theres a clip of him shadow boxing next to his opponent on a split screen, and there was ZERO question of who was the better boxer, and he ended up flooring the poor kid in 8 seconds. Huge waste of potential.
I've acquired a copy of this (won't say how) and can't wait to sit down and watch it.
