To me, this sounds like you want this "authority driven" thing to work for you when it makes sense to you, & not when it doesn't fit your agenda.
Frank Bush was given the keys to the car.
Every week, Kubiak stood at the podium and said Frank was doing a heckuva' job. That he liked what Frank was doing out there, blah blah blah.
So either Kubiak is a liar, or he truly believed that his d-coord was doing an OK job....but those pesky kids just weren't getting it.
You think Kubiak decided, on his own, without any intervention by owner & GM, to fire Frank Bush? Kubiak doesn't dispense with "his guys" very easily. All season long, he moaned and sadly said he sure doesn't hope nothin' bad happens at the end of the year because he sure does care about all his coaches--the guys brought in by him--and blah blah blah.
Kubiak is like a laser beam. It focuses narrowly on a single point upon a surface and bores a hole through it. However, none of the surrounding area is greatly affected by it. His hole he's bored is the offense.
He was trying to let Frank Bush laser beam that defense, giving him two years to make a go of it. It is up for debate if Kubiak would have fired Frank Bush on his own, with no outside arm twisting by owner & GM. But I think the ultimatum was laid down to Kubiak. Let's be grownups here and say this is the most likely scenario.
Lastly, Kubiak's affection for Steve Slaton (he was "the guy" who at least made Kubiak's life fairly easy for one season) is what drove Kubiak (IMO) to override Marciano and tell Joe that Steve would be fielding kickoffs. Kubiak is uber loyal, you know that TK. So he's not going to just have Steve ride the pine. How many carries did Steve get this season? Foster and Ward were our only two RBs who trotted onto the field. In fact, it was odd to see Slaton come off the field after a kickoff and Foster passes him on the way to the huddle. Steve Slaton, for all practical purposes, shouldn't be on this roster in 2011. But, I have a feeling he will somehow. Just a hunch. Gary will take him one more year in all likelihood. It's that loyalty thing. That "I brought you here, and I am responsible for you" thing.
A wise man once said "I am not responsible FOR you. I am responsible TO you." Which means that in our lives, those who have influence over our lives (coaches, teachers, bosses, etc.) are not ultimately held responsible FOR what happens to us--We're of our own accord and can make our own decisions in life. However, we are responsible TO people. Which means we ought to extend our best efforts to the person and try as hard as we can to set them up for success and then the person can hit it out of the park.
I'll just say that Kubiak strikes me as a person who has those two things confused. I think, IMO, he's got a thing for trying to give people a chance and then not having the guts to tell the person they failed.
Kinda' odd that this is how we also describe McNair on here, eh? Two guys who can't stop being loyal...even to their own detriment. They're coexisting equals, IMO, and that's why Bob likes Kubiak so much.
Enough is enough, except the guy with the checkbook doesn't think it's enough yet. We wonder "what WILL be enough?" but it's just becoming laughable at this stage. This, IMO, is the root of the anger of some people on here. An inability to throw away the night-night blankie and the pacifier and say "This is where the rubber meets the road."
The "Uber loyal" personalities in here, though, are not sure about that angle. I mean, heck...it's traumatic to make a drastic change and all. It's just downright traumatic. This is the mindset of a parent who feels he/she is responsible FOR their kid...even though the kid is 17 and ought to know better by now. Oh well, bail the kid out of jail. Kids are kids. This, IMO, is the predicament that our nation is in right now:
To what level am I ultimately responsible FOR and/or TO another person?
Go Texans.
