The Facts: Bills offensive coordinator Brian Daboll has won The Associated Press NFL Assistant Coach of the Year award.

Diehards Line: Daboll was named the winner at NFL Honors on Saturday. Consider it the culmination of three years working alongside Josh Allen, who entered the league as one of the rawest top-10 QB selections in recent memory. The two arrived in Buffalo just a few months apart, but success was not immediate. The Bills ranked 31st in offensive DVOA that first season. They were 21st last year. This year they were fifth. Accordingly, their scoring offense soared to second in the league at 31.3 points per game, an 11.7-point increase from the previous campaign. After reaching the postseason in 2019 on the strength of a top-ranked defense, the Bills won the AFC East this season and earned their first playoff win in 25 years largely because of their offense. The former longtime Patriots assistant had been an offensive coordinator for three NFL teams prior to joining Sean McDermott's staff. But never for longer than two years. Even a stint as Alabama's offensive coordinator, which produced a national championship, lasted just one season. But after drawing interest for a pair of head-coaching vacancies, Daboll will be back for morein Buffalo in 2021. That could be a super development for the Bills.
