I agree and this is where the "We hate everything Bill O'Brien" crowd start to speed into crazy territory. BoB is a slightly above average HC, he's not a great one by any means but he's also not the dumpster fire that some on here claim. If you look at his record and career, Texans and before, its actually pretty good on paper at least and if he was fired tomorrow yeah I believe he would have another HC job in the NFL, maybe not next season but when the next team where looking to make a change yeah he would be in that conversation.
So why would people think he is intentionally sabotaging players and the team? All that does is make him look bad and screw up his career. He knows he's not going to be with the Texans forever unless he is winning or at least competing for a SB year in and year out like Payton and BB. That's just the nature of the NFL so why destroy any chance at a job in the future? NFL teams, yes even the Texans, are not stupid, they may make some bad decisions but that doesn't mean they are stupid. If someone was tanking a team then other teams and the talking heads on ESPN and such would see it. I've heard plenty of them say he is doing a bad job coaching, much easier to believe and agree with, but I've never heard any of them say he is trying to sink the team.
