Jason La Canfora of CBS Sports reports that the Broncos have fired offensive coordinator Mike McCoy.

Adam Schefter confirms the news and adds that QBs coach Bill Musgrave has been promoted to interim offensive coordinator.

On Sunday, Ian Rapoport of NFL Media reported that there was “growing frustration” within the Broncos regarding their offensive scheme.

One issue for the team’s offense is that their offensive playbook is considered “unwieldy” and contained too much this year. Rapoport mentioned that at times this season, the Broncos’ playbook has featured more plays than even when Peyton Manning was playing for them, which seems crazy when you consider who inexperienced the team’s quarterbacks are.
