John Niland will be remembered in Dallas as one of the men who helped turn the Cowboys<\/a>into NFL<\/a> champions, but his family says the final chapter of his life was shaped by health problems that had followed him for years.<\/p>\n

The former Dallas Cowboys guard died Saturday morning in McKinney, Texas, at 82. His daughter, Haven Niland, confirmed the death, though the family hasn’t announced a specific cause.<\/p>\n

What they have shared is a picture of prolonged physical decline.<\/p>\n

\u201cI can’t remember a time when it didn’t impact our life,\u201d Haven told The Dallas Morning News. \u201cIt was a continuous discussion of dad’s got doctor’s appointments.\u201d<\/p>\n

She said her father underwent double knee and double shoulder replacements, later developed a staph infection in his spine and also dealt with mouth cancer.<\/p>\n

Niland also suffered cognitive decline<\/p>\n

The physical damage was only part of what the family endured. Haven said her father became increasingly confused and angry later in life, and the family believes chronic traumatic encephalopathy may have contributed.<\/p>\n

\u201cWe experienced a lot of hardships as a family,\u201d she said. \u201cHe was often confused later in life or angry for reasons he didn’t understand. We knew it was the CTE. We know it.\u201d<\/p>\n

CTE cannot be definitively diagnosed in a living person. Niland’s family plans to donate his brain to Boston University’s CTE Center for research after his death.<\/p>\n

Even while discussing those struggles, Haven made clear that her father’s legacy at home went far beyond football or illness.<\/p>\n

\u201cHe was the best dad,\u201d she said. \u201cHe was so wonderful. I mean, he was really bigger than life.\u201d<\/p>\n

She added that Niland taught his family \u201cthe things that really matter are family and your faith and just being kind to other people.\u201d<\/p>\n

Niland helped build Cowboys’ first championship team<\/p>\n

Long before those later health issues, Niland established himself as one of the best guards of his era.<\/p>\n

The Cowboys selected him fifth overall out of Iowa in the 1966 NFL Draft, making him the first offensive lineman the franchise ever chose in the first round.<\/p>\n

He became a fixture at left guard, starting 111 of 124 games for Dallas across nine seasons. Niland made six consecutive Pro Bowls from 1968 through 1973 and earned first-team All-Pro honors in 1969, 1971 and 1972.<\/p>\n

His defining team achievement came on January 16, 1972. With Niland protecting Roger Staubach, the Cowboys defeated the Miami Dolphins 24-3 in Super Bowl VI, securing the first Super Bowl championship in franchise history.<\/p>\n

He later finished his career with the Philadelphia Eagles in 1975 before retiring. Niland is survived by his wife, Shaughn, and daughters Jordan and Haven.<\/p>\n

No official cause of death has been released, but his family’s account makes clear that the former Cowboys star had been dealing with substantial health challenges well before his death.<\/p>\n","protected":false},"excerpt":{"rendered":"John Niland will be remembered in Dallas as one of the men who helped turn the Cowboysinto NFL…\n","protected":false},"author":2,"featured_media":408804,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[102,104,103],"class_list":["post-408803","post","type-post","status-publish","format-standard","has-post-thumbnail","category-dallas","tag-dallas","tag-dallas-headlines","tag-dallas-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/408803","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/comments?post=408803"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/408803\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media\/408804"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media?parent=408803"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/categories?post=408803"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/tags?post=408803"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
