T.J. Lavin, the BMX star and longtime host of MTV’s The Challenge since 2005, has seen all kinds of athletes compete in the series.

But if we consider the show a sport in its own right, could he declare that Johnny “Bananas” Devnanzio — who has won a record six titles — is one of the greatest athletes of all time in all of sports?

“I don’t know about that,” he told For The Win on Friday while promoting an eBay for Charity auction of Challenge memorabilia, in which the proceeds will go to non-profit Bright Pink in the name of late competitor Diem Brown. “He definitely adapts well, he plays the game good, but it’s a little different. He definitely embodies the politics side of it and we really don’t have that in professional sports. You can’t politic your way into a gold medal.”

“As far as The Challenge goes? He’s the greatest ever,” he added. “There’s no doubt about it. He adapts faster than anyone, he gets the game and plays it to the very line of the rules. They have to make Bananas rules just to make sure they covered all their bases because he’s so witty and smart about the game.”

Lavin also spoke about the “sweetest soul” of Brown, the Challenge competitor who died of ovarian cancer in 2014 at the age of 34. She had appeared on the show multiple times while battling the disease and inspired countless people in the process.

“She’s the most beautiful thing and all of a sudden you put in her story, and the stuff she had to overcome, and that makes her even more beautiful,” Lavin said. “She’s head and shoulders above everyone and in terms of, don’t give up, and never give up, never quit, she embodies that 100 percent.”

The auction, which includes game-worn shirts and signed items, will finish up Friday night.
