I post this on another thread...
Bruce Arians was on Golic and Wingo this morning and one topic was his first NFL head coaching gig. He said something that I've long wished Kirk would say. He told his coordinators and coaches, "You guys go do your jobs and I'll decide whether to go for it on fourth down."
My main reason for optimism with BFs hiring was that he might be the only candidate at this point in KFs career who could loosen the grip on the offensive reigns. When Norm Parker was the DC, I think Kirk felt he could pretty much say 'go do your thing' and not worry about the defense...and we had some great defenses.
I think we've seen some things in the offense we haven't seen in a long time (if at all), but it felt like a back-and-forth tug of war that is always going to be won by KF. But if we accept that Kirk is going to be here a few more years, I think BF is the only person with a chance to persuade KF allow changes on the offense. And that serves not only the current teams and staff, but I think it also would leave the team in a better position for whoever succeeds KF.
