The rise of the division rival New England Patriots under Bill Belichick and Tom Brady, along with numerous failed attempts at rebuilding in the 2000s and 2010s, helped prevent the Bills from reaching the playoffs in seventeen consecutive seasons between 2000 and 2016, a 17-year drought that was the longest active playoff drought in all major professional sports at the time. It was broken when the Bills secured a wild-card berth on December 31, 2017. On October 8, 2014, Buffalo Sabres owners Terry and Kim Pegula received unanimous approval to acquire the Bills during the NFL owners' meetings, becoming the second ownership group of the team after team founder Ralph Wilson. Under head coach Sean McDermott, the Bills returned to the AFC Championship for the first time since 1995 in 2021, losing to the Kansas City Chiefs 24-38.
