While there haven't been any concrete names mentioned as far as who Nebraska head coach Matt Rhule might look at for his now vacant defensive coordinator position, Brad White and DJ Durkin are officially off the board, if they were ever on it.
The Huskers have an opening after defensive coordinator John Butler was fired on Monday after just one season at the position and two seasons overall in Lincoln. Butler oversaw a defense that was routinely gashed by opponents' run game. His pass defense also took a couple of significant steps back late in the season as teams attacked his units' most significant weaknesses.
