The 2017 Buffalo Bills season was the franchise's 58th overall season, 48th in the National Football League and third full season under the ownership of Terry and Kim Pegula. The season was the first under the leadership of general manager Brandon Beane and head coach Sean McDermott. On December 31, 2017, the final week of the regular season, the Bills finally ended what would have been their 18-year playoff drought (previously the longest active drought in the NFL and the longest active playoff drought among the four major professional North American sport leagues) with the Bills winning 22–16 over the Dolphins and the Cincinnati Bengals upsetting the Baltimore Ravens 31–27. The Bills also improved on their 7–9 record from 2016 and clinched their first winning season since 2014 (when Doug Marrone was head coach). However, the #6 seed Bills lost the Wild Card game against the #3 seed Jacksonville 10–3, extending their playoff victory drought to 22 years.
