The move, obviously, paid off. Popovich has more wins than anyone in NBA history. And, when counting moves involving interim coaches, the next coaching change in the league will be the 300th since Popovich began coaching the Spurs. There have been 183 different coaches in the league since Popovich started, not including himself. Of those, 78 have coached multiple franchises in that span — Alvin Gentry, Larry Brown, Mike D’Antoni and Doc Rivers have coached in five different places over those years, and another nine coaches having worked for four different franchises in that time. “You’re always striving to be the best that you can be,” said New Orleans coach Willie Green, who is entering Year 4 with the Pelicans and has been in his job longer than half the other coaches in the league have had their current gigs. “But you take these jobs, understanding that they don’t have a long shelf life.”
