Sean McDermott completes Buffalo Bills coaching staff

Posted by: Chris Vannini on Monday February 13, 2017

Sean McDermott has completed his staff with the Buffalo Bills.

The 42-year-old McDermott spent the last six years as the Carolina Panthers defensive coordinator. That came after 12 years with the Eagles, where he moved up from scouting administrator to defensive coordinator. Now, he’s an NFL head coach.

McDermott takes over a Bills team that hasn’t reached the playoffs since 1999. Here’s the new Bills staff.

At 19 on-field assistants, it’s about an average size for an NFL staff, and it’s a mix of NFL coaches, college coaches and guys who have been out of the profession.

McDermott hired former Broncos offensive coordinator Rick Dennison to run the offense. Dennison is one year removed from winning a Super Bowl, but Gary Kubiak’s sudden retirement opened the Broncos staff. Marc Lubick also followed from the Broncos in a quality control role.

On defense, McDermott hired Leslie Frazier as defensive coordinator. Frazier spent one year as Ravens DB coach and was previously the Bucs defensive coordinator and Vikings head coach and defensive coordinator. Frazier also brought John Egoruwu as a defensive assistant, and Ravens OL coach Juan Castillo has also joined the Bills. Castillo previously worked on the Eagles staff with McDermott.

McDermott turned to the college ranks for a few assistants, including WR coach Phil McGeoghan (ECU), assistant DL coach Bill Teerlinck (Nevada), assistant DB coach Bobby Babich (FIU) and defensive assistant Jim Salgado (defensive assistant). McGeoghan previously worked in the NFL, and Babich is the son of linebackers coach Bob Babich.

Several assistants needed to find new work at head coaching changes elsewhere, including TE coach Rob Boras and DL coach Mike Waufle from the Rams, RB coach Kelly Skipper, assistant ST coach Matt Smiley from the Jaguars and LB coach Bob Babich from the Chargers.

Two coaches took 2016 off and have joined the Bills, including assistant OL coach Andrew Dees and defensive backs coach Gill Byrd. Offensive assistant Chad Hall is also in his first coaching job.

Special teams coordinator Danny Crossman was the only on-field assistant retained in the same role. McDermott from Panthers operations assistant Matt Worswich to Buffalo as assistant to the head coach.

Former NFL executive and current ESPN analyst Louis Riddick likes the group.
