NBA: Gregg Popovich done coaching Spurs, Mitch Johnson takes over

Gregg Popovich is stepping down as head coach of the San Antonio Spurs. He will now serve as the team's president of basketball operations. The Spurs announced this change on Friday. Popovich was the oldest coach in NBA history.

Mitch Johnson will take over as head coach permanently. He had been filling in for Popovich after his mild stroke in November. During that time, Johnson led the team to a 31-45 record.

Popovich has been present at the Spurs' facility recently. He will remain an important part of daily operations for the franchise. Sources say he has made steady progress in his recovery.

Despite wanting to return to coaching, Popovich realized he could not handle the demands anymore. His health has improved since his stroke, according to sources.

Mitch Johnson has spent ten years as an assistant with the Spurs. He played college basketball at Stanford and later joined the Oklahoma City Thunder's G League affiliate. Johnson also played professionally for three years before becoming an assistant coach with the Spurs' Austin G League team in 2016.
