During the Dallas Cowboys' 1971 title run, when the offense repeatedly followed No. 76, John Niland supplied the moving wall at left guard. Niland, the six-time Pro Bowl blocker who helped Dallas win Super Bowl VI, died on August 15, 2026, at his home in McKinney, Texas, with his family present, according to The Big Lead. He was 82.

Born in Quincy, Massachusetts, on February 29, 1944, Niland grew up in Amityville, New York, where he played fullback at Amityville Memorial High School and earned All-State recognition. His size and movement carried him to the University of Iowa as a fullback before the Hawkeyes shifted him to guard during his junior season. The change placed him on the path that defined his football life.

At Iowa, Niland developed quickly enough to earn second-team All-America honors in 1964 and first-team All-America and All-Big Ten recognition in 1965. He also represented the Hawkeyes in the East-West Shrine Bowl, the Hula Bowl and the College All-Star Game. University of Iowa Athletics later made those college seasons part of his Hall of Fame record.

The Cowboys used the fifth overall selection in the 1966 NFL Draft on Niland. Oakland also drafted him in the AFL, but his professional career took shape in Dallas, where he spent nine seasons as the Cowboys grew from contenders into champions.

Niland's specialty was movement at a position often measured by stillness. As a pulling guard, he left his spot on the line, turned the corner and cleared a path for the runner behind him. That work brought six consecutive Pro Bowl selections from 1968 through 1973 and three first-team All-Pro honors.

His defining stretch came in the postseason following the 1971 regular season. The Cowboys outscored three playoff opponents 58 to 18 on the way to the franchise's first Super Bowl championship. In its retrospective ranking of franchise greats, the Dallas Cowboys reported that several teammates considered Niland the team's best player during that run and that coach Tom Landry directed almost every play behind his lead block. Dallas completed the journey by beating the Miami Dolphins in Super Bowl VI on January 16, 1972.

The honors continued after the championship. Niland remained a Pro Bowl selection through 1973 and played his ninth Dallas season in 1974. The Cowboys traded him to Philadelphia in September 1975, and he started 13 games for the Eagles before his career ended. The NFL records 138 regular-season games across his 10 seasons, a body of work built almost entirely in the demanding interior of the offensive line.

Football institutions continued to return to that work. Iowa named him a first-team guard on its All-Century team in 1989. The Suffolk Sports Hall of Fame inducted the Amityville product in 1997, and the University of Iowa Athletics Hall of Fame followed in 2006. His name later appeared among the senior player nominees considered for the Pro Football Hall of Fame Class of 2026.

Niland's football record endures in the path of the pulling guard, the six straight Pro Bowls, the Iowa honors and the Super Bowl VI film of Dallas runners advancing behind No. 76. Those blocks joined the Cowboys' first championship to the work of a lineman whose most important achievements began by making space for someone else.
