He is certainly an interesting option, Daves. I think he was the assistant head coach with the Ravens in some of Lamar Jackson’s best seasons. I also remember him as a very good OC for Andrew Luck at Stanford.
He was OC for the 49ers under Jim Harbaugh, 2011-2014, adapting the offense from one that worked with Alex Smith to one that was better, then just as good with Colin Kaepernick, and riding a top defense to three NFC Championship games and a Super Bowl appearance.
Then he was OC for the Bills under Rex Ryan, 2015-2016. That team and offense were middle of the pack... but their QB was Tyrod Tailor.
Then he was Senior Offensive Assistant / Tight Ends Coach, Assistant HC and TE Coach, and finally OC for the Ravens under John Harbaugh with Lamar Jackson, 2019-2022.
Now he's OC of the Chargers.
So he's crafted offenses for and helped developed a diverse set of QBs, from Smith to Kaepernick to Jackson to Justin Herbert. He's learned from both Harbaughs, who build winning cultures. He knows how to get the most out of the running game and built an offense that featured tight ends in Baltimore.
He should have plenty of contacts from his time with the Harbaughs to build a quality staff.
One thing that makes me wonder a bit is that when Jim Harbaugh got ill during a game last season, it was Jesse Minter, and not Roman, that briefly took over as interim head coach. It might not mean anything at all. It just makes me think.
It is curious - though Minter is well qualified in his own right.
Not sure why he hasn't had more HC interest. He interviewed for the Browns job in 2020.
