Faith and family called him home. University of Colorado football head coach Bill McCartney achieved great success in the early ’90s, so his decision to quit in 1994 — at the peak of his career — came as a surprise. His religious conviction led him to organize Promise Keepers, a male Christian organization.

But he remains a controversial figure.
