1. Tom Landry (1960-1988)
They referred to him as the man in the hat. Many considered Landry as one of the most iconic head coaches in NFL history, specifically for the Dallas Cowboys.
Besides his record 20 consecutive winning seasons from 1966 to 1985, Landry won two Super Bowl titles (in Super Bowl VI and XII), five NFC titles, and 13 divisional titles.
"Landry built the 4–3 defense around me. It revolutionized defense and opened the door for all the variations of zones and man-to-man coverage, which are used in conjunction with it today. "- Sam Huff
Between 1966 and 1982, Dallas took part in 12 NFL or NFC Championship games. From 1970 to 1982, the Cowboys appeared in 10 NFC Championship games within 13 years. In 1990, Landry was inducted into the Pro Football Hall of Fame.
