Doug Marrone continues to round out his coaching staff with the Buffalo Bills, announcing 10 new hires Tuesday.

Marrone tapped into his old staff at Syracuse for four of those joining him with the Bills.

Three of the 10 coaches hired previously worked with new defensive coordinator Mike Pettine with the New York Jets.

Experience at the NFL level was not a requirement for Marrone. The 10 new hires have just 20 combined years of coaching experience at the NFL level, but 133 years of coaching experience in the collegiate ranks.

“When I began the hiring process for our staff, I sought after individuals that had a strong work ethic, passion for the game of football and experience — which are all qualities demonstrated in each of our new hires,” Marrone said in a news release from the team announcing the hires.

Joining the Bills will be:

• Defensive backs coach Donnie Henderson – A 28-year coaching veteran with 10 years of NFL experience and another 18 in the collegiate ranks, Henderson last year worked as the defensive backs coach at Syracuse. Henderson has three years of NFL experience as a defensive coordinator — two with the Jets in 2004-05 when Marrone was the offensive line coach, and another in 2006 with the Lions. He’s also been a defensive backs coach for seven seasons with three different teams (the Ravens, Jaguars and Cardinals).

• Running backs coach Tyrone Wheatley – Spent the previous three seasons on Marrone’s staff in Syracuse in the same role. Last season, the Orange averaged 187 rushing yards per game. Wheatley previously had a 10-year playing career in the NFL with the New York Giants and Oakland Raiders.

• Linebackers coach Chuck Driesbach – Driesbach is making the jump to the NFL after 36 years as a college coach, including 20 as a defensive coordinator. He most recently served as assistant head coach and defensive coordinator at Rice (2007-10).

• Linebackers coach Jim O’Neil – Has served as an assistant defensive backs coach the past three seasons with the Jets, where he started his coaching career in 2009 as a defensive quality control coach. The Jets’ pass defense finished second in the NFL this past season, allowing 189.8 yards per game.

• Tight ends coach Greg Adkins – Jumping to the NFL after 22 seasons as a collegiate position coach, the last four at Syracuse as offensive line coach and recruiting coordinator.

• Defensive line coach Anthony Weaver – Spent the 2012 season, his first in the NFL, as an assistant defensive line coach with the Jets. Weaver had a seven-year playing career in the NFL from 2002-08 with Baltimore and Houston. He played in 103 career games, making 98 starts.

• Assistant defensive backs coach Samson Brown – Joins the Bills after two years with the Jets as a coaching assistant.

• Defensive quality control coaches Jason Rebrovich and Brian Fleury – Rebrovich worked as a defensive assistant for the past two seasons under Marrone at Syracuse, while Fleury comes to Buffalo from Towson, where he spent the past four seasons as the secondary coach and special teams coordinator.

• Head strength and conditioning coach Eric Ciano – The lone member of Marrone’s staff who previously worked under Chan Gailey with the Bills, Ciano will be entering his fourth season with the team.

Marrone has yet to name positional coaches for the offensive line, wide receivers and quarterbacks. Offensive coordinator Nate Hackett worked with the quarterbacks at Syracuse.
