Not gonna vent here, but I'll say this... If you are the owner you don't make the decision based on whether you have another guy lined up. You make the hard call based on whether he's the right guy to lead this team. If Stan makes that call and keeps Fish I'll STFU and root for him. But there's no way I'll think it's a good decision.
There are plenty of options out there, or will be. You have first time head coach types who have made their names as coordinators. You have young retreads, some of which have only failed once or didn't get a true shake in their HC attempt. You have established retreads who might or might not be lured back, or who are awaiting another chance. You even have good collegiate options who will jump at an NFL job.
IMO never make a call based on thinking you have someone lined up, to me that's putting the cart before the horse. Is Fish up to snuff as your guy or not, that's the question!
