Manuel, who spent eight seasons in the NFL as a strong safety, worked as a defensive assistant under new Falcons head coach Dan Quinn for two seasons in Seattle, where Quinn was the defensive coordinator. Manuel also was a coaching intern under Quinn when Quinn was the defensive coordinator at the University of Florida.
The Seahawks tried hard Tuesday evening to keep Manuel, according to the source. Now, it appears Manuel joining the Falcons is inevitable. His interview is scheduled for Friday.
Quinn already hired former Washington Redskins defensive backs coach Raheem Morris as his assistant head coach/defensive pass-game coordinator. After his introductory news conference, it was made clear Quinn was still in the market for a defensive backs coach.
The team announced the additions of Richard Smith as the defensive coordinator and Kyle Shanahan as the offensive coordinator. Quinn retained special-teams coordinator Keith Armstrong, defensive line coach Bryan Cox, wide receivers coach Terry Robiskie, former assistant offensive line coach Wade Harman -- now the tight ends coach -- and assistant special-teams coach Eric Sutulovich. The other new additions include running back coach Bobby Turner and offensive assistant Mike LaFleur.
If Manuel is hired, the Falcons would be left with at least five coaching positions to fill: quarterbacks, linebackers, outside linebackers, offensive line and assistant offensive line. Fox Sports' Alex Marvez reported Quinn will bring Seahawks assistant offensive line coach Chris Morgan as his offensive line coach.
