What Gary is saying is:
"Believe in ME. Believe in what I have done, because that's what I will continue to do. What I need is for people to trust that my plans, which are UNCHANGING, will eventually be good enough once everything I've created comes together like it should."
Meanwhile, other HC's are trending toward being NOT as loyal to their own ideology. They're understanding that the best made plans often get scrapped for reasons outside their own control.
Gary Kubiak is of the old breed. The type of head coach who just knows that the system he learned, the system he played in, and the system he coached IS what produces champions. Like Tom Landry, and gawd I know that rubs people wrong, trust me, but like Tom Landry...Gary Kubiak is worshipping himself a little too much. He thinks his style of football, his style of offense, at the end of the day it's going to win because all it takes is players who are good enough (in his mind, just like Landry professed) to run HIS SYSTEM.
This is why Matt can only check to a RUN, and never to a new passing play. In Gary and Tom's world, coaches call the play and players run the play. Oh sure, you think you need to flip the run from the right and now run it to the left? Fine. But you are not going to assess and create, pre-snap, and try to adjust the overall play I, the coach, just called. No sir.
Which then tells you that whomever the QB is for the Texans, as long as Gary Kubiak is head coach, that QB will be a person who knows who butters the bread around there. "Be a good little soldier, do as you're told, I'll take the blame if it doesn't work."
This is how he shields his players from criticism, since obviously it really IS "All on him." Marciano, too. Marciano's faults are a result of Kubiak and he'll take the heat and he'll go to bat for Joe if Rick or Bob ever come knocking. Loyalty is good, but it's not the magic beans that it takes to grow a beanstalk to the heavens. And Gary, he'll never understand when it's time to cut bait.
