This was Coen's offense that much was clear. He didn't adjust well. His routes were not layered in typical McVay fashion, and they were slow developing routes forcing Stafford to hold the ball too long. Coen's only response were swing passes which for the most part were covered. This team is in big trouble if they continue to play Coen's small school offense.
Coen needs to go. His playcalling was very poor as was his game plan. It's all fixable, if McVay has the balls to make the changes. No playaction, nada. This is how I know this is Coen's offense. The route concepts were poor as well. Scrap Coen't playbook, dustoff last year's playbook and make him call from that. Better yet get a real NFL OC.
