The Broncos have fired offensive coordinator Bill Musgrave, according to Ryan O’Halloran of the Denver Post (on Twitter). This was the expected move after the team hired former 49ers assistant Rich Scangarello to serve as the team’s new OC. 
In theory, Musgrave could have stayed on with the Broncos in a different role, but Thursday’s move to dismiss him takes that option off of the table. From here, Musgrave can seek out other assistant jobs, and conceivably put himself in the running for some of the league’s remaining OC vacancies. The Bengals, Cardinals, Dolphins, Jets, Titans, and Cowboys are still in search of a new offensive chief.
Musgrave was elevated to Broncos’ OC position in the middle of the 2017 season when Mike McCoy was fired from the post.The Broncos went 2-4 after Musgrave took over play calling duties in 2017 and they went just 5–11 with him in 2018.
Musgrave was the Raiders’ offensive coordinator in 2015 and 2016 before the team declined to offer him a new contract following the ’16 season. Under Musgrave’s in ’16, the Raiders had the No. 6 ranked offense in the NFL.
No link for Bill here so I guess we will have to conduct a search at findagrave.
