The guy above wants to give McDermott most of the credit for Allen, so I'm going to give him most of the blame for not having the communication lines squared away in the most important game of his career.
I don't want him fired or anything. I'm just saying there's an argument to be made that he gets into big spots and gags them away.
You said McDermott is mostly responsible for Allen. That's the bad take.
I'll repeat- Josh Allen is 10x better at QB than Sean McDermott is at head coaching. I'm not going to debate this.
