"One Chicago" creator Dick Wolf was rooting for Brian Geraghty to play Officer Roman. He pushed for the actor to join the team and even made an unlikely exception to his standard seven-year contracts to let Geraghty join the cast on a year-to-year basis, per Deadline. For this reason, his decision to leave the show likely didn't come as much of a surprise to those working with him. Speaking with TV Line, executive producer Matt Olmstead explained how it all went down. "[Geraghty] had a lot of choices, and we courted him and pitched him what the show could be," said Olmstead. "And we were crossing our fingers that we'd get him ... He was like, 'I don't know if I can commit to a seven-year contract. This sounds great, but I've got to take it year by year,' which Dick doesn't do very often. But the deal was made."

Geraghty left the show after two seasons to pursue other options, Olmstead told The Hollywood Reporter. "[He] called like a gentleman and said, 'Hey, I got these other things going on. I feel like I've done my thing, and I'm just giving you a heads up that I'm going to go pursue those things,'" Olmstead said, (via Distractify). All told, fans got the chance to know Officer Roman and Wolf got to work with his actor of choice. It sounds like everything worked out for the best.
