Former Saints MLB Marvin Mitchell has signed in Miami, joining former teammate Reggie Bush.
Mitchell, 26, has been Jonathan Vilma's primary backup at middle linebacker since his rookie season. The Saints added Mitchell in the seventh round pick of the 2007 draft, when they drafted Mitchell and his college roommate Robert Meachem from Tennessee.
Mitchell started two games in his Saints career but played a lot of snaps in the Saints' hybrid 3-4 formations. He was credited with starts in the regular season opener and finale of the 2009 season, and was also credited with a start in Super Bowl XLIV when the Saints opened in a 3-4.
