The Atlanta Falcons promoted secondary coach Marquand Manuel to defensive coordinator on Friday.
The team also named Raheem Morris as wide receivers/passing game coordinator/assistant head coach. In addition, Doug Mallory was promoted to defensive backs coach to replace Manuel and former NFL standout Bryant Young was hired as defensive line coach.
Manuel, 37, spent the previous two seasons as the Falcons' secondary coach/senior defensive assistant.
Manuel was considered the top choice after the Falcons decided not to keep Richard Smith in his role as defensive coordinator. Smith could remain on head coach Dan Quinn's staff in an advisory position, but he plans to explore other options, according to ESPN.
The shakeup of the coaching staff comes after the Falcons' historic collapse in the overtime loss to the New England Patriots in Super Bowl LI.
Atlanta's defense surrendered 31 consecutive points and 546 total yards, including 466 passing yards to Tom Brady, in last Sunday's 34-28 loss in the Super Bowl. The Falcons led the Patriots 28-3 early in the second half before the largest comeback in Super Bowl history.
Manuel was the assistant secondary coach for the Seattle Seahawks when Quinn was the defensive coordinator there, and then followed Quinn to Atlanta in 2015. Manuel played eight seasons in the NFL at strong safety from 2002 to 2009.
Morris, 40, is entering his 15th year of NFL coaching experience while going into his third year with the Falcons. During Morris' first year in Atlanta, he was named the assistant head coach/passing game coordinator, where he helped out with the secondary and how to stop the passing attacks of the opposing teams. Morris was named the assistant head coach/wide receivers coach last offseason.
Morris spent three seasons as the head coach of the Tampa Bay Buccaneers from 2009-2011.
Mallory, 52, is entering his third season with the Falcons, after spending last season as the defensive assistant/defensive backs coach and his first year with the Falcons as the defensive assistant/linebackers coach.
Young, 45, brings five years of coaching experience to the Falcons. He worked under Quinn for two years (2011-12) during his three-year stay at the University of Florida (2011-13) as the defensive line coach. Young spent 14 seasons as a defensive tackle/defensive end with the San Francisco 49ers -- playing two years (2003-04) under Quinn, who was his position coach. Young, a four-time Pro Bowl selection as well as winning Super Bowl XXIX with the 49ers in January 1995, was a nominee for the 2017 Pro Football Hall of Fame class.
The Falcons will enter the 2017 season with two new coordinators, starting on Tuesday when outgoing offensive coordinator Kyle Shanahan was replaced by Alabama offensive coordinator Steve Sarkisian. Shanahan was named the head coach of the 49ers on Monday.
