Gennady Golovkin has played a significant role in the history of global boxing.

“In this century — definitely. He has also transformed the middleweight division's economy, drawing massive crowds in arenas worldwide. Fighters turned down bouts with high purses and the chance to compete for all his belts. I was the one trying to get other champions to fight him,” Leffler wrote in response.

As a reminder, Gennady Golovkin currently serves as the president of the National Olympic Committee of the Republic of Kazakhstan and also leads the Olympic commission of the newly established organization World Boxing, which aims to preserve boxing in the Olympic Games program.
