Not saying it’s necessarily appropriate but this is probably the main reason he does not get a HC job and most likely the assault against the female for which Colorado banned him for a year.

I think there has to be some reason no one has taken a chance on him. Off field stuff may be it. Either way, good on him changing things up. If he fields a decent NLF offense next season can show an ability to field an NFL average offense without Reid over his shoulder and Mahomes fixing everything, he'll get a head coach role without a doubt next offseason.
