The Texans want to talk to Whisenhunt, and some of what the search firm running their search has discovered about O'Brien's tenure at Penn State has caused some pause. He is very much a candidate, but Jed Hughes, who is running the process as a consultant, has not had a chance to schedule interviews with all candidates yet.
According to league sources, some of the concern around O'Brien includes the lack of success of Bill Belichick disciples and the heavy-handed nature of their power grabs in the past. Also, O'Brien's issues dealing with the AD at Penn State, and why two longtime trusted Penn State assistants recently walked away from the program without having other jobs lined up.
