I think the unraveling has already started with the front office. Someone's gonna be fired this offseason.
But Fish also has that additional concern with the players mailing it in. I do think he has their loyalty right now, but they know it's futile and this game vs Atlanta is going to be an immense challenge for them. They have a lot of guys who aren't gonna quit (AD, Ogletree, Joyner for example), but they also have some who are that type who might.
I think the OP might be correct overall. Offensively the players may have had enough here real soon, since I am sure they feel like they're going in with a BS plan for each matchup. Gurley has looked irritated all season. Goff being in there gives them some hope, but I suspect we're going to hear more and more grumblings as players talk to media types offline and that snowball starts rollin.
Good chance this is the beginning of the end, particularly if they get embarrassed by Atlanta at home which is a distinct possibility. Because the fans are something the team is very concerned with. And even worse they're probably gonna lose in Seattle this time around too, given how well the Shehawks are playing. It's gonna get worse IMO.
