Ewbank left the Browns in 1954 to become head coach of the Colts, a young NFL team that had struggled in its first season. In 1956, Ewbank brought in quarterback Johnny Unitas, who quickly became a star and helped lead a potent offense that included wide receiver Raymond Berry and fullback Alan Ameche to an NFL championship in 1958. The Colts repeated as champions in 1959, but the team's performance slipped and Ewbank was fired in 1963. He was soon picked up by the Jets, another struggling team in the AFL. While his first few years were unsuccessful, Ewbank helped build the Jets into a contender after signing quarterback Joe Namath in 1965. The Jets won the AFL championship in 1968 and went on to win Super Bowl III.
