Bill McCartney, the former University of Colorado football coach who became a prominent religious figure in the 1990s after founding the Promise Keepers movement, died Friday at the age of 84

After transforming the University of Colorado’s football team, he founded the Promise Keepers, a masculine revivalist group that drew millions of supporters.

He coached Colorado to a national championship in 1990. In retirement he led the Promise Keepers, an evangelical Christian group for “godly men.”

He led the Colorado Buffaloes to a national title and started a movement urging men to take responsibility for their faith, families, and communities.
