That isn't even remotely the same thing as demotion.
You are characterizing the move from OC/QB to OC/RB. Do you know what happened with the RB coach? Did they need to shift position coaches? Did Ruhle make the decision or do the hiring or did he have Satterfield make the decision?
After he got fired from Tennessee Tech, are you suggesting that Ruhle should have fired his OC at Baylor and pay a buyout to make Satterfield the OC? Did Satterfield have any recruiting connections to Texas? Would this have made any sense?
After the move to Carolina do you know that Ruhle keep him around? Did Satterfield want an NFL job and follow? Do you know if he applied for any other jobs but instead wanted NFL experience and exposure to a new system? Was Satterfield out of options and given a buddy analyst job?
Your bias is overwhelming because you're not willing to consider any other options. I'm not sure that Satterfield is the right fit here but I'm also not going to color all of my analysis to fit my agenda.
