Kelly continued playing at a high level, helping the Bills become one of the NFL's best teams for some time. From 1990 to 1993, the Bills appeared in four straight Super Bowls with Kelly at quarterback. Though the Bills failed to win every time, they remain the only team in NFL history to make it to four or more Super Bowls as of 2019. Long after retiring in 1997, Kelly is still considered the greatest quarterback in Buffalo Bills team history by many people, as he still holds many passing records for the team.
