Not to mention, knowingly leaving you QB on an island like that when you know unblocked pressure is coming is not the smartest thing to do if you want to keep him healthy. Martz became strangely obsessed with doing that trying to show the world how smart he was after the Super Bowl, got his HOF QB hurt, and ran out of town. Any one of those plays in which Goff got blown up by the pressure could have resulted in him getting hurt - even IF he had made a good throw for a completion. If McVay went into this game with a game plan that exposed Goff to this, that's coaching malpractice.
I haven't listened to the who show, but reading the OP and this thread, it seems like McVay wants to throw Goff under the bus while failing to acknowledge his own failings in going away from the run when it was working, then that's going to be a big problem going forward.
And where is the OC? Isn't he supposed to be somewhat of a consiglieri that whispers in McVay's ear to rein his some of his bad tendencies? Is he whispering and McVay is just not listening? What the hell is going on?
But I'll repeat again the obvious thing - if your running game is working and the opponent is not showing an ability to stop it, then Run. The. Goddamn. Football. You can come back and work on getting better against the zero blitz in practice and film study. Meanwhile, if you do run the football you have a chance of taking them out of their defensive gameplan and creating more favorable circumstances for the passing game.
