The Falcons are changing things up on defense following their loss to the Patriots in Super Bowl LI.
According to a report from NFL.com, the team has chose to move on from defensive coordinator Richard Smith.
Smith served as the Atlanta defensive coordinator for two seasons, coming to Georgia after four years as the Broncos' linebackers coach. The Falcons also matched their highest sack total (34) since the 2008 season but still finished ranked No. 25 overall in average yards allowed (371.2) and No. 27 in points (25.4).
"Defensive coordinator Richard Smith is being replaced while defensive line coach Bryan Cox is being let go by the team, a team source informed of the moves told NFL Network Insider Ian Rapoport on Wednesday".
Cox had spent three years with the Falcons, after spending a pair with the Tampa Bay Buccaneers where he coached their defensive line, and serving as their pass rush specialist. Atlanta is running his version of the 4-3 Under base with man-to-man and Cover 3 principles in the secondary.
Earlier Tuesday, the Falcons announced Steve Sarkisian would replace Shanahan as offensive coordinator, a role he has not held at the National Football League level.
Atlanta lost its quarterbacks coach Matt LaFleur to the offensive coordinator position with the Los Angeles Rams. The Falcons DC gig was the 61-year-old coach's third.
