The rebuilding Buffalo Bills will not promote their new head coach from within.

Former head coach Chan Gailey announced in his final news conference Monday that the Bills also fired his entire coaching staff. That means defensive coordinator Dave Wannstedt, among others, will not return to Buffalo in 2013.

The Bills are rightfully making a complete change to the coaching staff. They had no strong internal candidate to be considered for the head-coaching job, and firing everyone makes it easier for the next head coach in Buffalo to bring in his own people.
