Just to prove the point raised by both San Antonio’s Gregg Popovich and Miami’s Erik Spoelstra, here is a list of the Top 5 active coaches in the NBA who has stayed the longest with their team.
I would make a list of the current active coaches in the NBA with Finals experience(as a coach)..but then it turned out to be the exact same list. Exception would be Rick Adelman, although his Finals appearance was way back in 1992. If we base it on the past decade, there are only these five.
Mike Brown, NBA finals coach of Cleveland, is not considered active since he is just about to return.
George Karl was recently fired.
Coach Erik Spoelstra is only in his fifth season, and already he is number 3. Only Pop and Doc have stayed longer. Doc Rivers is rumored to leave the Celtics. If this happens, the two protagonists in the current Finals series will be the longest tenured coaches.
