Grudens schemes DO get guys open on a consistent basis, but that is a very superficial take either way. The WCO scheme Gruden offers puts players in the right areas of the field stretching the defense as the WCO demands. If you lack space to run after the catch the WCO is not the Offense for you. Gruden consistently accomplishes that in his schemes from what I can tell, execution issues aside.
My beef and I think the one most folks 'see' is that Gruden is sometimes too conservative, not trusting his Players to do their jobs. The result is a lot of check downs and protecting the balll (or the lead) instead of opening up the offense and playing chess with the defense. That is entirely on Gruden and McVay. They are shooting themselves in the foot trying to avoid mistakes while trying to get a rushing attack rolling as a priority.
News Flash: we are not executing our run blocks on a consistent basis so do not put MORE pressure on these young guys by allowing the defense to stack them up at the LOS. Its just time to move on and open things up with the pass first. Just trust Kirk.
All that bluster said, frankly Gruden is right to some degree too. He has needed to ramp these young guys up the way he has to date, but he really needs to get the foot off the brake more NOW and not just when we are down by 24. I get it that a guy like Ross is limited on the field as to what he can do and as a result what the OC can call. But he has a lot of packages at his disposal and he simply needs to let Kirk Cousins drive the car more often and determine if a play is going to work or not and just be more aggressive on his play calls. This team performs best when it is playing a more aggressive attacking style of play, and even if we turn the ball over more, it will GREATLY help the rush offense.
Its not the play calling. Its the "fear of failure" and you can't run this offense in that manner and wait until you have the ball control elements in place. We can't run the ball right now but we have to move forward nonetheless. The solution is simple in concept: "Free Kirk."
I don't worry about the Xs an Os, they'll come. What I to think is that the hardest thing to coach is the psyche of a team. A team that doesn't quite believe in itself won't handle adversity, and so a coach will try and coach that out of the game with the cautious plays you describe.
So the fact that we were able to come back from such a deficit, step on the gas a little, and get a great result might be the turning point for this team and a reason to open it up as you describe. It's also a real credit to the coaches, the GM, and the group of players they've put together.
But sooner or later we will need to be able to run the ball.
