Falcons shaking up defensive staff

FLOWERY BRANCH — After squandering a 25-point lead in the Super Bowl, the Atlanta Falcons are shaking up their defensive staff.

The team said Wednesday that coach Dan Quinn has dismissed coordinator Richard Smith and defensive line coach Bryan Cox, though there’s a chance Smith could stay with the Falcons in an advisory role.

The changes mean the NFC champions will have two new coordinators next season. Kyle Shanahan left to become head coach of the San Francisco 49ers and was replaced as offensive coordinator by Steve Sarkisian .

Also, the Falcons promoted Keith Carter to running backs coach with Bobby Turner reportedly leaving to join Shanahan’s staff in San Francisco. In addition, they will need a new quarterbacks coach; Matt LaFleur is expected to be named offensive coordinator of the Los Angeles Rams.

Smith will likely be replaced by a coach already on staff. The Falcons are considering defensive backs coach Marquand Manuel, linebackers coach Jeff Ulbrich and defensive passing game coordinator Jerome Henderson.

Manuel interviewed for the de- fensive coordinator post in Jacksonville last season.

The 61-year-old Smith served as defensive coordinator during Quinn’s first two seasons in Atlanta, after previously working as a linebackers coach in Denver. He has more than a quarter-century of NFL coaching experience.

Under Smith, t he Falcons showed significant improvement over the second half of the season and two playoff victories with a unit that often started as many four rookies and four second-year players.

But in the Super Bowl, Atlanta couldn’t protect a 28-3 lead midway through the third quarter.
