When I see the word referendum, I take it as a thumbs-up/thumbs-down on the regime. Outside of the Polian Super Bowl years, I can't think of a better time for the Bills front office. That doesn't mean victory is assured. Too many variables in football.
Are they? Are these Bills and those Chargers built the same way? Coached the same way? How many favorable/unfavorable calls did each team receive? What teams did they lose to? History may repeat but never in the same way.
