Former world heavyweight champion Evander Holyfield believes the failure of the U.S. boxing team at the Olympics can be traced back to an obsession with money.

　　Holyfield had predicted three American golds in boxing here but only heavyweight Deontay Wilder is still standing of the nine who began the tournament.

　　"They didn't do very well, not well at all," Holyfield, a bronze medallist at the Los Angeles Olympics in 1984, told Reuters at the Worker's Gymnasium on Tuesday.

　　"We've got to tighten up the amateur programme so that in four years we do a whole lot better.

　　"The problem is that these days it's all about money. When it's all about money this happens. The guys are just thinking about money. There's a kind of manipulation where the kids are being told 'go and turn pro, gold medals aren't important'.

　　"(The managers) don't want the guys winning golds because then they have to pay them more."

　　Holyfield racked up more than 150 wins as an amateur before turning professional in 1984 and believes that grounding enabled him to join the list of American boxing greats such as Oscar De La Hoya, Muhammad Ali and George Foreman, all of whom won Olympic gold medals.

　　"Back in the day, amateur boxing was on TV every weekend in the States," Holyfield said. "It inspired you to box.

　　"When you have a good amateur programme it helps develop well-rounded boxers. Look at the pro game now. Why do the championships change hands so quickly? It's because these guys don't know how to fight different styles.

　　"When you're a pro you avoid the fighters whose style doesn't suit your style, it makes them weak. Amateur boxing is harder than pro, you have to fight everybody in your draw.

　　"Without a good amateur grounding, it's the same as missing elementary and middle school and high school. It's your education as a boxer."
