I think part of what makes a coach great is understanding when to walk away. HoF coaches don't usually get fired multiple times.
Love Mike for the championships he brought to Denver, but also very glad he's somebody else's problem now.
Still amazes me how some omaners thought he'd literally be "coach for life" as if there really is such a thing in modern day football. Closest thing to that was Paterno and we all know how that story ended.
