The Buffalo Bills have been mostly fortunate to have great offensive coordinators helping Josh Allen since he joined the team in 2017. Allen, a first-round pick in the 2017 NFL Draft, entered the league with Rick Dennison as his offensive coordinator.
When it was clear that the team would need to go in a different direction, Brian Daboll was brought in during the 2018 offseason and his connection with Allen didn't immediately get off to the right start. By 2019, however, Allen and the Bills offense started to play better and by 2020, they had finished the year second in total offensive yards and in points scored.
