Every offseason, the NFL's coaching carousel starts spinning – with some leaving, perhaps involuntarily, and others jumping on board.

Coaching stability is something every team craves, but few can attain in the ever-changing world of professional football.

However, some franchises have managed to navigate the many obstacles and maintain a constant leadership presence on the sideline. And generally those have been the ones to show the most sustained success.
