If superstars are truly the face of the NBA, they're only afforded that lofty perch by the genius minds tasked with maximizing their effectiveness in the right system.
It's nearly a lose-lose situation for the coaches.
When the teams win, the players are the beneficiary of media praise and attention cast in the team's direction. When they lose, the coaches are chastised for their inability to mend their style of play to a roster that, at least in the fans' perspective, is simply too talented to not succeed.
Even relative success may not be enough to keep the coach in good graces. For some clubs, a playoff berth or development of young talent is all that's required—at least in the short term, that is. For others it's championship or bust, with no regard given to the myriad intricacies needed for a successful championship run.
But not all coaches have been subjected to this what-have-you-done-for-me-lately approach that has pushed some of their peers to the unemployment ranks. They've found the winning "system." It's really a constantly evolving style molded to the players on hand for that particular season.
In most cases it hasn't removed the threat of dismissal from the realm of possibilities. But in all of these cases, it has pushed these teams into heights that would be unreachable with lesser minds working the controls.
