damn how did it go so wrong for them? i know about schoob and the errors but their defense has turned to absolute shit as well. just baffling to me considering they have a solid roster
Kubiak has his shitty head coaching ability covered up by someone who plays at a high enough level to make his old school NFL ground game offensive schemes work - 2010 Arian Foster. Unfortunately Foster has to deal with a few injuries and the team manages to lose 50% of what was considered one of the better OLines (but more importantly a line that had meshed well and had the zone blocking scheme down pat). So now Kubiak has to rely more on his passing game...
Now instead of a game manager the Texans need a real playmaking QB. Which means it's Shoob time! Schaub, who was at least an above average game manager (and more than that for one season in 2009), also gets hit with several major injuries and an increasingly worse OLine and inconsistent run game. Whatever few things he did well around 2009-2010 haven't really been seen since.
And then there's the defense. Which went from absolutely completely godawful to godlike when Wade came in and brought Watt, Manning, and a good J Joseph with him to join a healthy (and overtraining) Cushing, Mario Williams, Demeco Ryans and Glover Quinn. The defense was so good it helped to make up for the holes that were starting to show up on the offensive side of the ball. Unfortunately look at how many of those names I just mentioned no longer exist on the Texans anymore (in that same capacity anyway: JJ has fallen off, Cushing is never healthy, etc.)
Basically the bandaids that were trying to keep the leaking ship together fell off.
