Bill McCartney, a legendary coach from Colorado, passed away at the age of 84 after fighting a battle with dementia.

Bill McCartney, the legendary Colorado football coach who led the program to its only national championship, passed away Friday night at the age of 84 after a long battle with dementia, his family confirmed in a statement.

The winningest coach in Colorado history, McCartney, passed away peacefully with his family by his side, the university announced in a statement.

At the age of 33, our father gave his life to Jesus, establishing a path for our family and others. We embrace his faith in Jesus and are confident that our Dad is now reunited with his cherished spouse, Lynne Marie, in Heaven.

Coach Mac's unwavering faith, boundless compassion, and enduring legacy as a leader, mentor, and advocate for family, community, and faith have touched countless lives. As a trailblazer and visionary, his impact was felt both on and off the field, and his spirit will forever remain in the hearts of those he inspired.

"We are saddened by his passing, but we also remember the remarkable life he led and the love he shared with all. We appreciate the support and prayers we have received during this time and request privacy as we grieve."

From 1982-94, McCartney served as coach at Colorado, where he guided the Buffaloes to three Big Eight titles, 10 consecutive winning seasons, and a national championship in 1990.

In 2013, he was inducted into the College Football Hall of Fame, maintaining his record as the winningest college football coach in Buffaloes history with a 93-55-5 record.

CU athletic director Rick George, who McCartney hired as a recruiting coordinator in 1987, expressed his deep sadness upon the passing of Coach Mac.

"I was fortunate to have the opportunity to say goodbye to Coach Mac in person last week. Coach Mac was an exceptional individual who taught me the significance of faith, family, and being a devoted husband, father, and grandfather. He instilled discipline and accountability in all of us who worked and played under his leadership. The impact that he had on CU football and our athletic department will be challenging to replicate."

The 1990 season is most notably remembered for McCartney leading Colorado to an 11-1-1 record and a win over Notre Dame, resulting in the program's only national title.
