Found some information on a potential addition by way of Texans TV. Interview with Drew Dougherty below where he mentions his 'right hand man' at Penn State.
Took me a while to get the name right but he is talking about Jim Bernhardt. Couple of articles about him below:
"But at none of those stops was he as busy, or juggle as much responsibility, as he does now in a non-coaching
role working with Bill O'Brien at Penn State."
"It’s a vital position for me,” O’Brien said in a recent interview. “You have to have somebody who can come in here and critique you. Who is critiquing the head coach? Obviously you have a boss, which is the athletic director. They’re in the Bryce Jordan Center and critiquing me on the overall program. Jimmy is critiquing me on a day-to-day basis, and not just critiquing me but critiquing the program in a constructive way," O'Brien told Audrey Snyder of PennLive.com. “He critiques me on X's and O's, on motivational things, overall recruiting ideas,” O’Brien said. “It’s maybe something in the weight room, something structurally in this facility. He helps make the schedule.”
