There are general managers in the NBA – like Larry Bird, for instance – who believe that coaches are hired on a temporary basis. Their voices become tuned out and a change is inevitably made after a handful of seasons leading the team.
While that sort of thinking is flawed, there is some truth to it.
When looking around the NBA, there aren’t a lot of coaches in the league that have lasted long.
Gregg Popovich has somehow beat the system and has lasted two decades as head coach of the San Antonio Spurs.
