Ringer article about what to look for in a Head Coach during this hiring cycle, and this section stood out to me as to why only fools would consider moving on from Shanahan for [insert reason]:
"The coach ends up being the voice of the franchise. Can they keep everyone grounded when things are going well? Will they take responsibility when things go badly?
The second question is important because things always go badly (eventually). Bill Belichick just went 12-22 over the past two seasons. Andy Reid was 12-20 in his final two years with the Eagles. Mike Tomlin's Steelers have gone seven straight seasons without a playoff win. And those are the great coaches. Just think of everyone else! The NFL is hard, and there are so many variables—injuries, schedule strength, officiating, luck—that determine wins and losses. You'll have seasons when the ball doesn't bounce your way. During those times, you need a coach with a steady hand. Someone who points the finger at themselves and is capable of coming up with solutions for righting the ship. The best coaches come in on a Monday morning with the same demeanor whether the team won or lost the day before. Consistency matters. It's a long season. Having someone with a volatile personality at the top can wear on everyone. Leadership is hard to evaluate, but the truth is it's the only quality that really matters if you are trying to achieve sustained success."
That describes Shanahan perfectly. And that's not even considering his x's and o's skills, which is outstanding.
