If using last years final ranking then yes, that makes sense. I took the question to mean will it improve from the first games or “ now” through the end of this season. The question wasn’t asked in say, June. I’m not even sure where the Bills defense stands now as far as rankings go, but it’s safe to say most fans have concerns. I think this is more than just about defensive rankings anyway. The Bills defense has failed in the playoffs even when they were highly ranked statistically.
