NBA coaches rise and fall every year. According to our very own Tom Ziller, the average tenure for an NBA coach is 2.4 seasons. That, quite literally, is much shorter than I ever would have guessed. Coaches like Erik Spoelstra, Gregg Popovich, and Rick Carlisle are, a.) insanely good at their jobs, and, b.) blessed to work for patient front offices.
