RIP: NFL coach Dan Reeves dies at 77. “Reeves both played and coached in the league for more than three decades and included nine Super Bowl appearances and two wins. He played for and later became an assistant coach of the Dallas Cowboys and went on to become head coach of the New York Giants, the Denver Broncos, and the Falcons. His two Super Bowl wins were during his time with the Cowboys. He coached the Falcons to the 1999 Super Bowl, in which they lost to the Broncos. He retired from coaching in 2003 but stayed involved in the sport through broadcast and consulting. The Broncos and the Falcons both honored him for his impact on their teams.”
