Well, as long as this thread is about O'Brien, let me add a completely unsubstantiated rumor of which I have only heard by word of mouth from one person. She says as a volunteer for the Houston livestock show & Rodeo that O'Brien was very rude to her in asking for directions and said he was the head coach of the Texans and deserved better treatment (or something like that).
You heard it here first folks, on the TexansTalk BBS. A internet rumor that can't be proven from someone most of you have never met. LOL
But seriously, she did say that about him. She now thinks O'Brien is a complete turd and hopes the Texans go 0-16 this year. But she's also an Eagles fan so there's that as well.
I think it is obvious that she is John McClain's secret source of NFL breaking news.

I can believe the 'rude' part, but I do not believe that O'Brien actually said that he's the head coach of the Texans and deserves better treatment. That sounds like a nugget of reality wrapped in a layer of embellished hyperbole.
But regardless, I have no doubt that Bill Parcells, Bill Belicheck, and many other winning coaches probably upset the delicate sensibilities of a few grocery sackers and waiters.
