For the first time in 29 years, the head coach of the San Antonio Spurs will not be Gregg Popovich. The Hall of Famer stepped away from the post, taking a front office position. His replacement, Mitch Johnson, who served as Popovich's interim as he dealt with health issues this season, has big shoes to fill on the sideline.

Gregg Popovich has stepped down as coach of the San Antonio Spurs, ending a three-decade run that saw him lead the team to five NBA championships, become the league’s all-time wins leader and earn induction into the Basketball Hall of Fame.
