Scangarello spent two seasons in San Francisco, joining the team during Shanahan's first offseason.
After injuries to Garoppolo and Beathard last season, Scangarello helped undrafted free agent Nick Mullens go from third-stringer to starter.
"With the addition of Rich Scangarello as our offensive coordinator, we're getting an experienced coach who was a trusted and valued assistant with Kyle Shanahan for three seasons", said Broncos head coach Vic Fangio in a team release. He was not going to take over play calling duties from head coach Kyle Shanahan with the 49ers.
Scangarello would seem a good fit for an offense that general manager John Elway declared needs to modernize to keep up with teams around the National Football League who are all-in on the run-pass option, among other innovations.
First up for Scangarello is finalizing the rest of the offensive coaching staff.
The Denver Broncos have locked in on their coaching staff that will be tasked with the responsibility of building the Broncos back to relevancy after a disastrous previous regime.
Fangio and Scangarello have never coached together, but once the 49ers granted permission for him to interview earlier this week, Scangarello traveled to Denver and was the only known candidate to be interviewed.
This completes the Denver Broncos coordinators.
The 49ers likely will move one of their current assistants to that spot, either Mike LaFleur, who has the title of wide receivers coach/passing game coordinator, or Mike McDaniel, who is the team's run-game coordinator. But Fangio and the Broncos were clearly impressed by Scangarello's work with the 49ers' rotating cast of quarterbacks and his overall offensive vision.
Ted Monachino was recently hired as Kansas State's defensive coordinator.
Defensive line coach Jay Rodgers is the only defensive position coach still in place. The news was first reported Wednesday by ESPN.
"I have a ton of respect for him, and it's mutual between both of us". Solomon Thomas, the No. 3 overall pick in the 2017 draft, has not developed into a significant contributor.
