The NFL coaching landscape underwent a massive transformation last week when Bill Belichick and Pete Carroll left the New England Patriots and Seattle Seahawks, respectively.
Mike Tomlin of the Pittsburgh Steelers now stands as the NFL’s longest-tenured head coach, and there are questions about his future, as well, after 17 seasons with the franchise.
All of this speaks to the unpredictable and often limited shelf life for head coaches in today’s NFL. And it gives one an even greater appreciation for the success Belichick achieved over 24(!) seasons at the helm in New England.
