BOB has not built the team that we all want, but it is a Division Winning Team and if you think back before he got here, what would we have given for a Division Title. Those were few and far between under Kubiak.
Kubiak won exactly the same number of division titles his final three years here as O'Brien has his first three. The Texans have won 4 of the last 6 division titles, and the two they didn't were the last season for Kubes, and the first for OB, so I can't agree with the "What would we have given for a division title" angle given that prior to OB they'd won two of three.
Kubes (biggest) downfall was not getting the QB situation solved after Schaub got fatally (in football terms) injured. O'Brien has the same issue, but to this point, he's been able to go no worse than 9-7 in any of his three years, and has avoided the crash and burn season that precipitated both Capers and Kubiak's departure.
I honestly don't know how much goodwill he's built up in the almost three seasons he's been here, but I know that if Savage isn't the answer, and/or the Osweiler experiment doesn't see radically different results next season, it's an issue he's got to solve.
Beyond that, I really give him some credit. Granted, his offense has been putrid this season (and that may be giving it more credit than I should), but while still far from great, I think the first two seasons it was respectable considering it was led by guys named Fitzpatrick, Hoyer, Mallett and Keenum. As mediocre as that list is, I was both surprised and disappointed to see that this season it got unquestionably worse. I was in support of the signing of Os - not because I was convinced he was the next Manning, Rodgers or Brady, but because I did feel like he had a decently high ceiling, and his floor was (at worst) better than the list of career backups listed earlier. I was obviously very wrong about the second part of that, and the first part isn't looking real great right now either. Still, a big percentage of the folks who followed up the KC playoff disaster saying even a swing and a miss is better than what's been happening at QB now seem to be of a different mindset. I'm still glad they made a significant move to improve the QB situation, and I'm still glad it didn't involve trading draft choices (likely an unrealistically large amount of draft choices) to move up and grab one of two QB's who have to this date not convinced me they're going to be top 10 NFL QB's (although in fairness, neither has convinced me that they're not either).
Anyway, because of Brock's 2017 cap hit, and what I consider the unlikely possibility that a QB will be drafted high (a combination of a gut feeling, and the opinion of "experts" that I trust that 2017's draft is a weak one for QB's), it looks like (to me anyway) that unless Savage is the answer, or Brock can be made to be the answer (one of which I give less than a 50 percent chance, the other I give far less than a 50 percent chance), we'll have to wait until 2018 for another chance to meaningfully address the situation, and see if OB can do what he needs to still be around at that point.
Okay, if you've read this far, you've got to be tired of hearing (so to speak) me, because I know I am.
