The Bills probably aren't upset that they are bringing back offensive coordinator Brian Daboll and defensive coordinator Leslie Frazier for their fourth and fifth seasons, respectively, in Buffalo. After all, why get rid of the coordinators who helped create 2019's second best defense and 2020's second best offense?
However, it seems as though the Bills do want to bring a change to the NFL that might make it easier for qualified coaches like Daboll and Frazier to become head coaches if their teams make a postseason run, according to Albert Breer of SI.com.
It's not only Daboll and Frazier that would have been affected by such a rule this season. Think about Kansas City Chiefs offensive coordinator Eric Bieniemy, who was shut out from a head coach position once again despite receiving labels as a top candidate for a number of needy teams out there. Nathaniel Hackett, the Green Bay Packers' offensive coordinator, was interviewed by the Atlanta Falcons but didn't get any other requests. Super Bowl winning offensive coordinator Byron Leftwich of the Tampa Bay Buccaneers didn't get an interview at all.
Breer added the full list of assistant coaches who received interviews despite being in the Conference finals of their respective divisions.
Should this proposal become adopted into the league's rules, there may not be any more excuses as to why Eric Bieniemy and others are left without a new job following extremely successful stints.
