My point isn’t to try to get to root cause immediately, but rather to determine an objective measure to see if 1) the Bills have a trend that is improving, degrading, or staying steady, and 2) to see how the Bills compare to the rest of the league. We know all our team’s injuries by heart and how much they hurt, but how are they in relation to everyone else? That helps you understand if the Bills are an anomaly. If they aren’t, then using injuries as an excuse is just that— an excuse.
