Brandon Staley and Christian Parker interviewed for Defensive Coordinator, Doug Nussmeier interviewed for OC; all on Feb 16

Staley's lack of defensive production as a HC makes me nervous but Underhill did a study on young OC'S that got hired as head coach and while the hit rate was fairly high, the ones that did fail also had young first time DC's. Parker as DC combined with Moore could just be too much youth and inexperience in the coaching staff. At least Staley brings some experience even if his experience wasn't great.
That's actually why I would prefer Staley to be Assistant HC and a position coach. Splitting those duties would greatly help CKM manage the team without taking the focus away from the defense. Parker could focus only on DC duties where Staley would likely have to do both as DC.
