Duncan, 43, spent his entire career playing for the Spurs, officially retiring after the conclusion of the 2015-2016 season.
“It is only fitting, that after I served loyally for 19 years as Tim Duncan’s assistant, that he returns the favor,” Popovich said of Duncan’s hire, jokingly.
Popovich took over as head coach for San Antonio in the middle of the 1996-97 season, and drafted Duncan the following year.
The pair went on to win 5 NBA Championships and made the playoffs each season. Duncan collected two MVP awards, 15 All-Star nods, and is a sure-fire Hall of Famer.
Duncan will be a familiar face, as some of the players on the roster played with Duncan while he was still an active player, such as LaMarcus Aldridge and Patty Mills.
