He wasn't to blame for 2 of those INTs last week, nor for the loss at Detroit, but it is crucial that he wins to maintain the job. I'd say next week's home game vs Carolina is a must-win for him. In fact, if it's not going well, it will be the first official snap for Goff at some point in that game.
And tbh even in winning Case has to play well. Lot of pressure on him right now IMO.
With Fish I agree it's about the final record. I don't expect Stan to fire him during the season unless this team continues an extended losing streak that ties his hands. But I do think it's going to take 9 or 10 wins at a minimum for Fish to get that extension. No way he gets it otherwise.
