This is a huge problem. Anytime Mickey gets criticized for anything the default response is "oh he doesnt do anything". Mickey or Khai Harley has to be replaced with someone who knows football and not just rely on the HC to be a GM as well.
Why does Mickey or Harley have to be replaced in your opinion? Why do you disagree with Bill Parcels belief that the HC should be the one who picks players?
