The Ravens will promote assistant head coach/tight ends coach Greg Roman to the role of offensive coordinator, Jeff Zrebiec of The Athletic tweets. Coach John Harbaugh confirmed the change to Zrebiec, which will be the first of many on the offensive staff. 
Roman’s promotion takes Marty Mornhinweg out of his role as OC, but Mornhinweg has been asked to stay on board in a different capacity, Zrebiec tweets. More shuffling could take place in the coming days as running backs coach Thomas Hammock is said to be a top candidate for the head coaching job at Northern Illinois.
In 2018, the Ravens’ offensive staff had to reinvent everything on the fly as Lamar Jackson took over for Joe Flacco. Roman played a sizable role in getting the team to adjust and the Ravens believe he is the man to guide them into Jackson’s first full season as a starter.
Roman, who turns 47 this summer, served as the 49ers’ OC from 2011-2014 and the Bill’ OC from 2015-2016. He hooked on with the Ravens in 2017 and nabbed an AHC title before the 2018 season.
The staff’s reorganization and Harbaugh’s role in the shuffling may be a sign that he is staying put. There have been tons of trade rumors surrounding the coach, but the two sides have been discussing an extension over the last week.
I don’t see how Roman keeps getting OC jobs he hasn’t done anything impressive. As a niner fan he drove me nuts, I was so happy when he was gone. Dudes a hack good luck with him Ravens
Might be better suited for building an offense around Jackson. He did fairly well with Tyrod Taylor in Buffalo. And I think he’s a slight upgrade over Mornhinweg.
When you don’t have any talent on the Niners, I think it would be pretty hard to implement your system
No talent? He was there with frank gore, boldin, Crabtree, and Vernon Davis, a good oline and kaep. I’d say there was plenty of talent for him to work with even though kaep didn’t work out. His system failed in sf
