82 is no age when you think what the body goes through on that line for ten years. My dad was a rugby prop and ended up with dementia at the end, so reading that Niland's family are donating his brain to the CTE study hit harder than I expected. Didn't even support the Cowboys, just know what that last stretch looks like from the inside.
Their story
John Niland was an American football player who anchored the left side of the Dallas Cowboys' offensive line through the team's rise in the late 1960s and early 1970s. A six-time Pro Bowler and three-time first-team All-Pro guard, he started for the Cowboys when they won their first Super Bowl,…
John Niland was an American football player who anchored the left side of the Dallas Cowboys' offensive line through the team's rise in the late 1960s and early 1970s. A six-time Pro Bowler and three-time first-team All-Pro guard, he started for the Cowboys when they won their first Super Bowl, beating the Miami Dolphins in Super Bowl VI in January 1972.
He was born John Hugh Niland on 29 February 1944 in Quincy, Massachusetts, and was placed for adoption at the age of two. He grew up in Amityville on Long Island in a family with little money, began working at nine, and only learned he had been adopted when he applied for a driving licence at 16. At Amityville Memorial High School he was an All-State fullback, and he went on to the University of Iowa on a football scholarship. Converted to tackle and then guard, he was a second-team All-American in 1964 and a first-team All-American in 1965, despite playing on losing teams.
The Cowboys made him the fifth overall pick in the 1966 NFL Draft, the first offensive lineman the franchise had ever taken in the first round. He started four games as a rookie and became the permanent left guard in 1967, playing in the Ice Bowl NFL Championship Game against Green Bay that season. Known for his quickness as a pulling guard, he went to six straight Pro Bowls from 1968 to 1973 and was first-team All-Pro in 1969, 1971 and 1972. In nine seasons with Dallas he never played on a losing team, reached the playoffs eight times and made 111 starts in 124 games. He was traded to the Philadelphia Eagles in 1975, played one season there and retired after a knee injury in training camp in 1976.
His life after football was difficult for a time. He later spoke openly about cocaine and a fast lifestyle, and in 1988 and 1989 he served 11 months in a federal prison camp after being convicted of submitting a false financial statement to obtain a loan. After his release he turned to his Christian faith and rebuilt his life, working in sales for the Arrow Magnolia chemical company and later for a concrete company.
Niland died at his home in McKinney, Texas, on Saturday 15 August 2026, at the age of 82, with his family around him. No cause of death was announced, and his family said his brain would be donated to the Boston University CTE Center for research. The Cowboys called him the core of Tom Landry's greatest teams and a tough, team-first player.

In their own words
“I felt I could fit in right away. I think all my teammates, at least the ones on offense, we all had confidence in each other.”
On joining the Cowboys, in a 2023 interview quoted by DallasCowboys.com
“We were pretty confident, not cocky, just confident.”
On Super Bowl VI, quoted by DallasCowboys.com

Sorry about your dad, that's rough to watch happen.
