#5: The Spurs have coaching stability
Unlike almost every other coach in the NBA, Popovich actually has job security. That might not seem like a big deal when it comes to Wembanyama, but it definitely is. The Spurs have had the same coach for the last 27 years, the longest active tenure in North American sports as well as NBA history. During that time, Popovich transformed the franchise's culture, turning it into the envy of the NBA.
Although he may only coach for another season or two, what he has built should remain. After all, he will also likely have a say in who replaces him, a rarity in the league, and Wembanyama can rest assured that whoever the next coach of the Spurs is, it won't be someone who will only be around for a season or two before being replaced. That should ensure stability and hopefully mean little change once Popovich decides to retire from coaching altogether.
Compare that to stars such as Giannis Antetokounmpo, who has had seven coaches in 10 seasons, and Trae Young, who has had four coaches in five seasons. Coaching stability is an underrated aspect that Popovich and the Spurs can provide Wembanyama that most other teams simply can't, and that should only benefit him as he begins his NBA career.
