I think you guys are reading stuff into the show. Obviously, using logic we know a crew is not a crew when there is only guy in it! The show only showed the characters that were apart of the story, but that doesn't mean they didnt exist before hand! Patsy Parisi wasnt in the first 2 seasons, but does that mean he didnt exist before season 3? Same thing with Ralph Cifarreto, we didnt know he was in Richies crew until season three but does that mean he wasnt there?

Curtos crew had more than him, the writers just never thought to bring any of them into the story.
