With the Buffalo Bills reportedly adding Dave Wannstedt to their coaching staff, many questions will need to be answered regarding the structure of Buffalo's defensive coaches under - or perhaps in Wannstedt's case, around - coordinator George Edwards.
Wannstedt, who reportedly has the title of Assistant Head Coach/Linebackers, does have experience working with one other Bills coach aside from Chan Gailey: current outside linebackers coach Bob Sanders.
Sanders served as the Miami Dolphins' linebackers coach from 2001 through 2004, when Wannstedt was Miami's head coach. During that time frame, the Dolphins ran Wannstedt's 4-3 defense, with Sanders coaching up the likes of Zach Thomas, Derrick Rodgers, Morlon Greenwood and Junior Seau.
Sanders was Buffalo's defensive line coach under Dick Jauron in 2009, and was retained by Gailey entering the 2010 season to coach the Bills' outside linebackers. It is not yet clear if Wannstedt's title gives him authority over all of the Bills' linebackers - outside and inside - but the fact that he and Sanders have worked together before might mean that Sanders has a role on the team no matter what Wannstedt's role entails.
