I believe Romo was on the PS and ran the scout team his rookie year. Carter being the starter and Hutchinson was the lone backup on the active roster.
Ok, looks like Romo was indeed on the 53 active roster in 2003. If you scroll down the page of this link you can see he's listed on the 53. Best I could find...no idea why he's not listed on other rosters.

Just curious. Why can't I find Romo on any of the rosters or depth charts from 2003? I'm 95% sure he was a Cowboy in 2003 and never heard anything about him being on the practice squad. Can someone help here?
