Alvis Forrest Gregg (October 18, 1933 – April 12, 2019) was an American professional football player and coach. A Pro Football Hall of Fame offensive tackle for 16 seasons in the National Football League (NFL), he was a part of six NFL 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. Gregg was later the head coach of three NFL teams (Cleveland Browns, Cincinnati Bengals, and Green Bay Packers), as well as two Canadian Football League (CFL) teams (Toronto Argonauts and Shreveport Pirates). He was also a college football coach for the SMU Mustangs. As a head coach, he led the 1981 Bengals to the Super Bowl, where they lost to the San Francisco 49ers, 26–21. Early life and college career Born in October 18, 1933 in Birthright, Texas, Gregg attended Sulphur Springs High School in Sulphur Springs and played college football at Southern Methodist University in Dallas. Playing on both the offensive and defensive line at SMU, Gregg earned All-Southwest Conference honors in his final two seasons. Playing career Gregg was a key player in the Packers dynasty of head coach Vince Lombardi that won five NFL championships and the first two Super Bowls. He played mostly at right tackle, but also filled in at guard. He earned an "iron man" tag by playing in a then-league record 188 consecutive games in 16 seasons from 1956 until 1971. He also won All-NFL honors for eight straight years from 1960 through 1967 and nine Pro Bowl selections. Gregg closed his career with the Dallas Cowboys, as did his Packer teammate, cornerback Herb Adderley. They both helped the Cowboys win Super Bowl VI in January 1972, making them the only players (along with former teammate Fuzzy Thurston, who was on the Baltimore Colts NFL championship team in 1958 and Tom Brady of the New England Patriots and Tampa Bay Buccaneers) in professional football history to play on six NFL title teams. Gregg wore the number 75 for 15 seasons in Green Bay, but that number belonged to Jethro Pugh in Dallas, so Gregg wore number 79 for his final season in 1971. It has been reported that Vince Lombardi said, "Forrest Gregg is the finest player I ever coached!" but official Packers team historian Cliff Christl can find no evidence of Lombardi ever saying or
