A lucky gold medal is still much more than 99% of the former amateurs achieve, so give him some break.
The pro ranks and the Olympic ranks are totally not comparable. Look at what Cotto did to the guy who beat him in the Olympics or trying to get to the Olympics. If he is trained and managed right, he will do good things.
Torsten May, Roy Jones Jr´s Korean opponent in the finals, etc., etc. In every Olympic Games there is AT LEAST one boxer who get's a gift (and at the same time his opponent gets screwed). There is always SOME controversy.
