With the firing of Chuck Driesbach on Monday, the Buffalo Bills now have two open spots on their coaching staff.
The team could opt to fill their vacant spots at linebackers coach and wide receivers coach from outside the organization, bringing new voices into the room.
Another option is to promote from within, allowing younger coaches an opportunity to advance. If the Bills choose to go that route, here are the top options for the vacancies:
Jason Vrable, offensive quality control: Vrable has close ties to the current coaching staff, serving in a variety of offensive assistant roles on Doug Marrone's staff at Syracuse from 2009-10. He later served as offensive coordinator and quarterbacks coach at the University of Charleston (West Virginia) from 2011-12 before re-joining Marrone and offensive coordinator Nate Hackett with the Bills. He would be the natural in-house choice to replace Ike Hilliard as wide receivers coach.
Brian Fleury, defensive quality control: Like many of the Bills' coaches, Fleury came up through the college ranks, coaching at Maryland, Sacred Heart, and Towson before joining Marrone this season. The former college quarterback worked closely with outside linebackers coach Jim O'Neil this season, tutoring the Bills' pass-rushers. With Driesbach no longer in the fold, one option would be to move O'Neil to inside linebackers coach and have Fleury take over with the edge players.
