LAS VEGAS -- As Gennady Golovkin stood in the glare of bright television lights helping to beam his image to the world, the boxer's closest confidant and most trusted adviser stood alone in the theater's shadowed corner.
There in the darkness, Max Golovkin shed some needed light on what has made his twin the world's most explosive boxer.
"Nobody knows about it because camp is always closed," Max Golovkin said. "No one knows how dedicated and focused and concentrated he is."
While operating as an unbeaten, three-belt middleweight champion, Gennady Golovkin (37-0, 33 knockouts) is pleased to reveal his talents for all inside the ring.
He returns there Saturday night at T-Mobile Arena for his most important bout yet, against Canelo Alvarez, Mexico's popular former two-division champion.
What stirs Golovkin, what makes him so committed to his craft and what unleashes the viciousness that resulted in 23 consecutive knockouts with 18 consecutive middleweight-title victories, are motivations he keeps from public view.
For example, after his first daughter was born last week, Golovkin did not want to talk about it.
"My focus is on boxing. Boxing -- business," he said.
Although the response could have come off as heartless, there could also be a cultural aspect at play. Golovkin is from Kazakhstan and many Eastern European fighters, including the dominant heavyweight Klitschko brothers, have struggled to find an audience in the U.S. because they have not made emotional connections with boxing fans.
Golovkin has participated in two previous HBO pay-per-views, and although each fight was competitive and action-packed, neither generated more than 200,000 buys. Alvarez (49-1-1, 34 KOs) had 1 million buys for his May victory over countryman Julio Cesar Chavez Jr.
