San Antonio Spurs head coach Gregg Popovich has a Hall of Fame resume after 22 successful seasons with the organization.
The 69-year-old bench boss has led the Spurs to five NBA championships and 19 50-plus win seasons, but could be close to calling it quits.
"I don't know the answer," Popovich said when asked about his decision to return next season, according to The New York Times' Marc Stein.
Popovich is still flourishing in his role despite losing Tony Parker, Manu Ginobili, and Kawhi Leonard this past summer. He has surrounded LaMarcus Aldridge and DeMar DeRozan with a group of young shooters and aging veterans, winning 15 of the Spurs' last 21 games.
If this is Popovich's last season in the NBA, the legendary bench boss will still be on the sidelines for USA Basketball after committing to coach during the 2019 FIBA World Cup in China and 2020 Olympics in Tokyo. He was named as Duke head coach Mike Krzyzewski's replacement in 2015.
