During a Pro Football Hall of Fame playing career, he was a part of six championships, five of them with the Green Bay Packers before closing out his tenure with the Dallas Cowboys with a win in Super Bowl VI. He went on to serve as head coach of three NFL teams (Cleveland Browns, Cincinnati Bengals and the Packers), as well as two Canadian Football League teams (Toronto Argonauts and Shreveport Pirates). He was born in Birthright, Texas and attended Sulphur Springs High School. Gregg played college football at Southern Methodist University. Gregg was a key player on the Packers dynasty that won five NFL championships and two Super Bowls in the 1960s.
