Daniel Patrick Quinn is an American professional football coach who is the head coach for the Washington Commanders of the National Football League (NFL). He came to prominence as the defensive coordinator of the Seattle Seahawks from 2013 to 2014, coaching a defense later known as the Seattle Cover 3 that featured the Legion of Boom secondary. In both years under Quinn, Seattle's defense lead the NFL in total defense and made consecutive Super Bowl appearances, winning the franchise's first in Super Bowl XLVIII.
Quinn then served six seasons as the head coach of the Atlanta Falcons from 2015 to 2020, with the team appearing in Super Bowl LI at the end of the 2016 season. Quinn would make the playoffs only once more in Atlanta, resulting in his firing early in the 2020 season.
