Victor Wembanyama's early days in the National Basketball Association will be overseen by one of the league's most legendary coaches, outspoken Gregg Popovich, who helped transform another French teen, Tony Parker, into a superstar.

Popovich, the 74-year-old son of a Serbian father and Croatian mother, is the longest-tenured coach in any major American sports league, having guided the Spurs since 1996.

With discipline and priorities formed while at the US Air Force Academy in the 1960s, Popovich has become a five-time NBA champion head coach, a three-time NBA Coach of the Year and in August will be enshrined in the Basketball Hall of Fame.

"What makes a great coach is getting a lot of young men and helping them become men, adding to their life," said NBA guard Dwyane Wade.

"Coach Pop has done an amazing job of helping young men become grown-ass men."

Golden State coach Steve Kerr, who won two NBA titles playing under Popovich, praised his impact.

"He's amazing," Kerr said.

"There are just so many people like me whose lives have been impacted so dramatically and so positively by Pop. One of the most influential people ever in my life. I owe him so much."

Popovich mentored top draft pick Tim Duncan in 1997 and Parker when he came to the NBA in 2001.

"I loved playing for Pop," Parker said.

"Pop was huge. I always trust Pop's judgment."

Popovich accepts the challenge of a new generation with Wembanyama, the most talented prospect since LeBron James with size like Duncan and Parker-esque skills.

"He has still got it. He can do this for a lot longer," Kerr said.

"One of Pop's great abilities has been his willingness and eagerness to adapt."
