I will say, I agree with you on that.
I don't disagree with the fact that he had to churn the roster. It was a bad and hard decision and he needed to do it.
But he played a bit too hard the Jimmy Johnson/Bill Walsh mold even though he never played for Jimmy or Bill.
Both of them did that, but you're right, they did it mostly behind closed doors and didn't let anyone see. He never played directly for either but he knew they did it and he played the role but for a stage.
I get it, it's the harsh reality of football and it's why Johnson and Walsh are NFL Hall of Fame Head Coaches and why Sanders wears rings that their successors won.
But no, you're right, don't do it in public.
