As they normally do, the Bills will probably fall behind by a couple of touchdowns, at which time Joe Brady will have to stop calling wide receiver screens and James Cook running off tackle on first down. Hopefully the game will still be in reach, and if so, at some point in the second half, Allen will take over from his offensive coordinator, and the Bills will start gaining chunks of yards and scores on the strength of Allen's ability to create something out of nothing.
Against good teams, the team's main strategy seems to be to try to keep the games close and let Josh Allen perform heroics at the end. It's a bad strategy, but more often than not it works especially when Allen feels as if he has something to prove against a good team like the Patriots.
