In 1960, he became the first head coach of the Dallas Cowboys, a position he held for 29 seasons (1960–88). The Cowboys started with difficulties, recording an 0–11–1 record during their first season, with five or fewer wins in each of their next four. Despite this early futility, in 1964, Landry was given a 10-year extension by owner Clint Murchison Jr. It would prove to be a wise move, as Landry's hard work and determination paid off, and the Cowboys improved to a 7–7 record in 1965. In 1966, they surprised the NFL by posting 10 wins and making it all the way to the NFL Championship game. Dallas lost the game to Lombardi's Green Bay Packers, but this season was but a modest display of what lay ahead.
