Unless the posters on this board are football coaches, former coaches, or have been involved in hiring football coaches, and can objectively evaluate football personnel decisions and football coaching talent, then I would let our FOOTBALL COACH makes the decisions on who belongs on his staff.
Someone also said Coach Strong was being hard-headed.....how the heck do you know that? Have you had conversations with him or know someone who has confirmed that? If not, then quit speculating about why he has not chosen an OC.
