Completely and unequivocally disagree.
If you take that approach with Fitz, then you have to take it with everyone in every situation and not just in coaching.
But, let's take coaching as an example.
Derek Leonard is an outstanding high school football head coach at Rochester. Been there for many years and won a bunch of titles at that 4A school. If 8A Loyola Academy or 8A Lincoln Way East or even Eastern Illinois University offer Derek a job as their head coach, you are saying he should take it and it says something about him if he doesn't.
In that respect, perhaps I do agree with you about it saying something about the man. If he turns down such a job, it says to me that he is happy at Rochester. It says that he believes there are more important things in terms of the quality of life that he wants for him and his family than succeeding at the next level. It says that he enjoys what he is doing and he realizes that the grass is not always greener on the other side.
Fitz has a family. He is part of a community. His kids are in local schools. He belongs to a church. He could keep all those same things with a Bears job, but are the Bears all that great of an opportunity? They don't exactly have a stellar history of longevity in the HC position. They have a GM who passed on Mahomes, traded up and gave away a ton for a relatively unproven Mitch Trubisky. Really? He should want to work for that guy?
Has it occurred to you that some guys are cut out to coach younger players? Or that some coaches PREFER coaching younger players?
