Johnson, 38, has been with the Spurs organization since 2016, serving as an assistant coach and later stepping in as interim head coach during Popovich's health-related absence in the 2024–25 season. Under his interim leadership, Johnson earned respect for maintaining the team's culture and guiding young talents like Victor Wembanyama and Stephon Castle.
