Earl Edwin Morrall (/ˈmɔːrəl/; May 17, 1934 – April 25, 2014) was an American professional football player who was a quarterback and Most Valuable Player in the National Football League (NFL) for 21 seasons, both a starter and reserve. He started for six teams, most notably with the Baltimore Colts and the Miami Dolphins. He became known as one of the greatest backup quarterbacks in NFL history, having served in the capacity for two Hall of Fame quarterbacks in Johnny Unitas and Bob Griese. An injury to Unitas in 1968 saw Morrall step in to start the season that saw the Colts to a 13–1 record (along with an MVP for Morrall) that saw them win their first NFL Championship in nine years before ineffective play in Super Bowl III saw him benched for Unitas. Two years later, in Super Bowl V, Morrall came off the bench for an injured Unitas and kept the Colts in the game before they ultimately won on a last-second field goal. In his first season with Miami in 1972, he came off the bench when Griese became injured early in the year, with Morrall winning all nine starts; Morrall started the first two playoff games, with Griese playing in each game before being named the starter for Super Bowl VII, where the Dolphins completed the only perfect season in NFL history,
