U.S. handball coach Javier Garcia-Cuesta believes that Cleveland Cavaliers star LeBron James has the potential to quickly become the best handball player in the world, according to the Washington Post.

“Maybe six months,” Garcia-Cuesta said. “This is just a hypothetical. He has everything. When you see him playing, your mouth drops.”

The belief that a basketball player like James has the physical tools to dominate the sport is not just held by the U.S. coach, but is actively thought about by handball players.

“We always talk about it: If the Americans really wanted to play handball, they would be amazing,” Denmark center back Morten Olsen said. “They have so many good athletes, and really big, strong athletes. It would be a big problem. Playing against LeBron James, that would be hard.”

Toronto Raptors guard Kyle Lowry, who is competing with the U.S. men’s basketball team in Rio, believes that American basketball players could transition into handball if they wanted to.

“You’re talking about another sport with running and jumping, changing direction and throwing a ball into a net?” Lowry said. “Yeah, I think we could figure it out. How much do they make?”

James has been arguably the most dominant player in the NBA over his career, being named NBA MVP four times and wining three NBA titles.

The U.S. handball team, on the other hand, has historically struggled, missing the last five Olympics.
