I'm a believer that as a fan of this team it's possible to be disappointed with a coordinator and yet the league will view them differently. It's the Josh Allen effect, making everyone around him look better. But when you carry the kind of point differential that the Bills do from season to season, many teams will probably look at our coordinators as a massive upgrade over whatever they are running. As @DapperCam mentioned however, as is the case with Daboll, some of these guys may get hyped up more than they deserve to be.
