 After three middle-of-the-pack seasons, Colts owner Carroll Rosenbloom fired Weeb Ewbank and replaced him with Don Shula, who at the time was the youngest head coach in NFL history (33 years of age when he was hired).The Colts finished 8–6 in Shula's first season at the helm, good enough for only third place in the NFL's Western Conference, but they did end the season on a strong note by winning their final three games.The season was very successful for Unitas personally, as he led the NFL in passing yards with a career-best total of 3,481 and also led in completions with 237.
