If the coach calls the plays, why have an offensive coordinator? I doubt we see a change in the offensive scheme this year and doubt Mcdermott was limiting anything. All the stats about us having a good offense are because of Josh Allen being the best QB of our generation. He blows everyone else away, and is hindered by terrible coaching.
This is because Josh Allen is a generational QB. Not because of our coaches. We would have a top 10 offense with you or me at O coordinator.
