Yeah and that's why 10 years with one team is like some invisible cutoff for a HC. After ten years you're out of ideas and go back to old playbooks. We saw it with MM. He just got stale. But there are exceptions. Tomlin in Pittsburgh is the most obvious example. He's taken some pretty average teams the last 5 years or so and at least got them in the playoffs. That's harder than managing a very talented team.That's what I like about Joe as well.
Its really fascinating to me how most older coaches refuse to adapt and grow with the changing of the times.
Outliers like Belichick and Reid were humble enough to adjust their ego, which is essential to sustain excellence.
And it might be true at the coordinator level. I think if a guy is good and has 5 or 6 years under his belt, HC should be in the near future. and then you get guys like Rich Bisaccia who are happy to stay as a coordinator. Nothing wrong with that as long as the units keep producing. That's one reason guys move around. I mean could Bisaccia have asked for a bigger challenge than GB STs? Doubt it.
