The same people will also be "angry" and "mad" if the Texans lose... saying that Kubiak can't do anything right. When in reality, they'll be mad at him if they win as well...
That was not on the O-line. Was a "coverage" sack... or the receivers weren't "open" enough for Keenum to pull the trigger. Or Keenum just didn't pull the trigger because he's getting more and more cautious each week.
