The interesting thing about that article is that it sounds like O'Brien hired Bernhardt to keep him in check, and to cuss him out when needed.
That. Is. Fantastic.
Word on Twitter is that Bernhardt is coming to the Texans in some kind of role.
The idea that O'Brien doesn't surround himself with "yes" men, and actually have people he respect tell him when he may be making mistakes, is a sign of confidence and maturity.
The funny thing is, I used to say that Kubiak needed someone like this on his staff. Back when Kubiak was regularly screwing up challenges, I used to say that he needed a "big picture" person on staff, up in the booth during games, to tell him when to challenge something; and to tell him - during the week before games - that his strategy needed to be tweaked.
