And Eric Studesville, who served as interim head coach for the final four games last season, is returning at the Broncos' running backs coach.
New coach John Fox announced eight members of his new staff Monday, six of whom he inherited in Denver and two members of his staff from Carolina, where he coached the last nine seasons.
Other holdovers are Clancy Barone (tight ends), Wayne Nunnely (defensive line), Brian Callahan (offensive quality control) and Jay Rodgers (defensive quality control). Fox is bringing offensive line coach Dave Magazu and wide receivers coach Tyke Tolbert over from Carolina.
Fox is still filling some positions, including defensive coordinator and special teams coach.
McCoy, who will call plays, is both a holdover and an old hand in Fox's systems.
He served seven seasons under Fox in Carolina as offensive assistant, quarterbacks coach and passing game coordinator before joining the Broncos as Josh McDaniels' offensive coordinator in 2009.
"I might even know him better than the people here in the Broncos organization. I definitely hold him in high regard," Fox said last week.
McCoy has overseen a half dozen 3,000-yard passing seasons from quarterbacks, including four from Jake Delhomme and two from Kyle Orton. McCoy wasn't the primary play-caller until McDaniels' firing Dec. 6.
Under his tutelage, Tebow threw four TD passes and ran for three TDs while starting the final three games of last season. Tebow's 82.1 passer rating was the highest of the NFL's eight rookie starting quarterbacks, and Orton ranked fourth in the NFL with 281 yards passing per game.
Magazu became Carolina's offensive line coach in '07, which coincided with the Panthers' shift to the zone-blocking scheme that took hold in 2008. Since then, only the New York Jets have rushed for more yards than Carolina, which became the first team ever to have two 1,100-yard rushers in the same season (DeAngelo Williams and Jonathan Stewart in 2009).
Fox said he'd return the zone-blocking, one-cut scheme to the Broncos, who abandoned that style under McDaniels in favor of a power scheme that often stalled behind a young offensive line.
Studesville went 1-3 as interim head coach after McDaniels' dismissal and was one of five candidates who interviewed for the head coaching job that went to Fox.
Studesville's appointment means Fox won't have his longtime lieutenant Jim Skipper in that role in Denver. But Skipper might still join Fox's staff, although he has opportunities elsewhere in the NFL to coach running backs.
