I realize many of the older guard, like myself, may jump on you for this post. But the next 2 weeks will tell me a lot about the direction of this organization. If we go out and play poorly during these 2 home games, then the changes you mention make sense.
The current regime seems to be spinning their wheels without any answers. I think others could do more with our current talent. Our roster is far from perfect but coaches must ID the strengths of the roster and call plays to take advantage of those talents.
If the run blocking is fair to good, you run. If the pass blocking is poor, you continue to run to set up the pass. Not the other way around. You do not shove an entire pass happy playbook down the throat of a 1st year QB and ruin his develpment and psyche. Especially with these pass blockers.
If you struggle against the run on D, you don't continue to call outside blitzes, leaving the middle of the field exposed.
The starters seem very frustrated and look towards the staff for answers. If they can't provide any, then doubt sets in and team confidence is gone.
The next 2 weeks should answer a lot of questions.
