Seems every new HC feels the need to start from scratch - and invent things just for the "building" excuse.
I'm not football smart - but it seems to me that canny, intuitive, clever Coordinators - preferably with an established, winning characteristic - which will be accompanied USUALLY by a large paycheck is the way to go.
The second thing is that the most successful coaches - even those we had during out Golden years - entered with some ideas - but with an open mind to be open to new things that work - and not have a firm, hardened mindset on HIS way of doing things.
Schnellenberger was innovative that way - JJ came in with a gunslinger approach to just win and gave the players a lot of leeway, Erikson didn't rock the boat - he just improved it, and Butch from under JJ embraced a lot of JJ's ideas on how to make the most out of what he had - not force the team into a hard-frame drawing.
I think Mario is a good coach - just not a great coach.
And I don't know where in Hades we'll find a great coach. We have some good talent - but I see too many dumb mistakes - DUMB mistakes - that show talent over smarts and discipline are not successful.
We play - dumb.
