Kirk hasn't played like a franchise QB but there is plenty of blame to go around:
Against Dallas, 73% of the plays were pass plays to 27% run.
Cowboys vs. Redskins - Box Score - September 18, 2016 - ESPN
Two of those runs were Kirks's and were called passes so the break down is actually 75% pass and 24% run.
What the hell?
Kirk was not playing well and our O line was out playing their D line on every level and Jones was running better than he ever has. He was getting yards after contact and falling forward.
The play callers did nothing to take some of the pressure off Kirk with the run game which was working better than it has in a while.
There is a lot, A LOT, of blame on the play calling, whether it was Jay or McVay it was bad.
With the game as close as it was throughout, a more balanced approach was possible.
As mentioned in other posts, the 1st and goal from the 6 was infuriating. 3 straight passes against some guys they picked up at Home Depot playing DLine.
Mike Tomlin would have planned on going for the TD in 4 downs.
