This has zero to do with O'Brien, why is it that every time someone talks about a game where the defense didn't do its job its automatically taken as defending the offense. News flash, if RAC and the defense was as good as some here think then we could win a SB on the defense alone. Steelers did it, Ravens did it, Broncos did it so why can't the Texans if the defense is so amazing. We have certainly spent enough draft capital on the defense. Even the most hardcore of BoB hater admits he stays away from the defense so why aren't they winning us rings?
Colts did exactly whatever they wanted on offense, when they wanted to score points they did, when they wanted to burn the clock they did. By the time of the second half they were also looking to save their players for the next playoff game so they didn't see a reason to stay aggressive. Kubiak use to do that all the time, in fact its what he liked so much about Manning because he knew when to just be a game manager and not try to be a hero. BoB tries to do it but he does it to early with not enough of a lead. About the only team that really stays aggressive and keeps trying to put nails in a closed coffin is the Pats.
On that day the defense sucked, the offense sucked, BoB sucked, RAC sucked, Watson sucked, the Oline sucked, the RBs sucked, the TE and receivers sucked (Nuk did ok for being injured), the QB rushing sucked, the coverage sucked. In short the Texans sucked. It was a true team effort to all lose together and they did just that.
