Because he thinks he's the smartest guy in the room. Doing things differently is a way for him to show it.
Of course, that only works if he succeeds (which he isn't).
I'm gonna be following new Packers OC Adam Stenavich, among others. He was listed as an up and comer / possible future head coach in last year's articles.
Heck, we got one Packers line coach already. Why not collect the whole set?
That's actually a pretty good idea.
Mind you, if he fails to replicate his KC success, that could wind up hurting thim. I suppose that's the risk you take though if you're betting on yourself.
His contract with the Chiefs has expired, so technically he could end up somewhere else this year, though not as a head coach.
That said, I expect he'll return to being the Chiefs OC with a new contract.
But you never know...
