We need a HC. No doubt coordinators are hired all the time to be HC's and some turn out great. But with Jerry, that just plays into his hands of not really having a quality HC. Just like with Gailey, Campo, Wade and Garrett he has proven he basically wants a glorified coordinator as opposed to having to hire a real HC.
But I've pretty much given up hope we'll ever go out for a quality HC again as long as Jerry is alive. We'll keep settling for Jerry-friendly easy to control puppets. And I wouldn't be one bit surprised if the next HC isn't already on staff. It makes it even easier for Jerry to just promote a current assistant like he did with Campo and Garrett than to have to hire someone he doesn't already know. If I were a betting man I'd put my money on Callahan
or Marinelli.
