ENGLEWOOD, Colo. (AP) — Jerry Rosburg was more than three years into his retirement following a 40-year career as an assistant coach when a phone call in mid-September interrupted his morning coffee as he sat on his lakeside deck in Florida. It was his old friend George Paton, who needed a favor: Would Rosburg come to Denver to handle game management duties for Nathaniel Hackett, who had stumbled through his first two games as the Broncos' coach? Rosburg accepted the offer and the challenge, setting in motion an unimaginable journey that led to an even bigger request from Paton this week.
