Following the Colts' first NFL championship, the team once again posted a 9–3 record during the 1959 season and once again defeated the Giants in the NFL Championship Game to claim their second title in back to back fashion. Following the two championships in 1958 and 1959, the Colts did not return to the NFL Championship for four seasons and saw a transition from head coach Ewbank to a young Don Shula in 1963. In Shula's second season the Colts compiled a 12–2 record, but lost 27–0 to the Cleveland Browns in the NFL Championship. In 1965 the Colts played the Green Bay Packers in a playoff to determine who would go to the NFL Championship game. The Colts were leading 10–7 over the Green Bay Packers with two minutes left to play when the Packers' kicker, Don Chandler seemed to barely miss a field goal. The referee called it good however, and the Packers went on to win the game in overtime. The error precipitated changes to the rules: the NFL decided two referees would judge future field goals, and that the uprights should be raised by ten feet. In 1968 the Colts returned with the continued leadership of Unitas and Shula and went on to win the Colts' third NFL Championship and made an appearance in Super Bowl III. In 1968, Unitas was injured and replaced by Earl Morrall who became the league's MVP.
