Here's an argument in favor of it.
I tend to agree, Kubiak is good for the Texans. He did a lot for this team both after the 0-4 start and at the 3-7 mark. The problem most people have is how/why did we get to the 0-4 point to begin with. Ike was a big deal, and I don't think it can be overstated. And as to the 3-7 mark, its a 3-3 record removing the 0-4 start.
Looking toward a less eventful 2009 and beyond, I think he'll do a lot with a little on offense, which is good.
The defensive side of the ball troubles me. His mentor didn't focus on defense, and apparently he's following right in the footsteps of Papa Shan. I understand he's involved in the offense, and that's where he's focused, but can we get a decent DC and a couple key players on that side of the ball and turn this defense around?
Just like the suggestion I saw in the game-day threads about just onside kicking every kickoff, since we're gonna let them run down the field at will anyway. How about we blitz on every down, and move Frenchy to free safety? This way he can at least LOOK in the right place (the ball), so we're half way to a decent player (if he just uses his arms we'd be all set).
