Dolphins lose executive to the Bills.

The Buffalo Bills have hired former Miami Dolphins player personnel director Joe Schoen.

Schoen, who had just completed his ninth season with the Dolphins, was named Buffalo’s assistant general manager Sunday.

The hiring is Brandon Beane’s first move since taking over as the Bills’ top executive last week.

Schoen joined the Dolphins in 2008 after spending his first seven years in the NFL with the Carolina Panthers, the organization Beane worked for before becoming Buffalo’s general manager.

During his tenure in Miami, Schoen oversaw both the college and pro scouting departments. He served as a key liaison between Miami’s coaching staff and the personnel department.

At this time it is unclear what the Dolphins will do to replace Schoen, who served as general manager Chris Grier’s second in command.

Anthony Hunt, who has been with the Dolphins for 23 years, is entering his fifth season as the director of pro personnel.

And Adam Engroff, who has been with the Dolphins for 18 seasons, is entering his second season as the team’s director of college scouting.

Both could be promoted if the Dolphins want to elevate an inhouse candidate.

Grier could also formally hire his father, Bobby Grier, who spent decades working in and running NFL front offices before retiring after serving as Houston’s senior personnel advisor two years ago. Bobby Grier worked with the Dolphins as a consultant this past draft.
