Not sure what Kubiak has to do with anything. . .
Let it go, man
You need to watch more NFL news than just the Texans.
There are many other head coaches willing to say a lot more than the mundane mumbles that emanate from O'Brien's mouth every week.
I absorb NFL news from a variety of source daily, and I can straight up tell you that there are coaches like Andy Reid and Sean Payton that will give a lot more insight than the belligerent BS that O'Brien puts out there. O'Brien is surly and arrogant at his press conferences. John McClain said he's one of the worst HCs he's had to cover in many decades of being an NFL reporter. And he's not the only member of the press to notice it.
Honestly, I'm a little surprised that the Houston Texans, Inc. marketing empire allows it, but clearly "Texans worthy" died with Bob. It is what it is.
