The Buffalo Bills have fired offensive coordinator Rick Dennison.

Buffalo reached the playoffs this season but their offense ranked 26th in offensive DVOA.

"We're not satisfied with the whole offense, and it wasn't just about [quarterback] Tyrod [Taylor]," general manager Brandon Beane said Tuesday. "There's a lot of hands in the cookie jar, so to speak, and [coach] Sean [McDermott] and I, we're going to talk about everything, and we know we have to get better on offense, on defense, on special teams. We are far from a finished product."

Dennison joined the Bills last January after Sean McDermott replaced Rex Ryan as coach.
