The Las Vegas Raiders have filled their final coaching vacancy, hiring Mike Sullivan as quarterbacks coach. Sullivan, a veteran offensive assistant with two Super Bowl rings and a national championship, will mentor top overall pick Fernando Mendoza.

Sullivan joins Klint Kubiak’s staff after initially agreeing to serve as assistant wide receivers coach at Rutgers. The 59-year-old Army alum has deep ties to the Raiders’ coaching staff and front office.

He coached alongside Kubiak in Denver in 2018, when Kubiak was an offensive assistant and Sullivan was the Broncos’ quarterbacks coach. Sullivan also spent the last four years with the Pittsburgh Steelers, three as quarterbacks coach and one as a senior offensive assistant.

Sullivan won Super Bowls with the New York Giants in 2007 (as wide receivers coach) and 2011 (as quarterbacks coach), both victories over Tom Brady and the New England Patriots. In 2011, Eli Manning had arguably his best season under Sullivan’s tutelage.

He has coached at the college or NFL level since 1993, winning a Division I-AA national title as defensive backs coach at Youngstown State in 1997. Sullivan served as offensive coordinator for the Tampa Bay Buccaneers (2012-13) and the Giants (2016-17).

The Raiders were the only NFL team without a designated quarterbacks coach since Kubiak’s first full staff was announced earlier this month.
