Two questions here really.

Firstly, do top 3 guys ever run private crews? Like an underboss or consigliere (permanent, not acting) that has guys reporting directly to them? Seems to make sense for their personal earnings, but would it throw the whole structure out of whack?

Secondly, are the guys that surround top dogs day-to-day all made? I've often wondered about drivers, bodyguards etc. Its a menial job that takes them away from earning on the street, so seems wasteful to use made guys, but equally its a privilege to get that close. A bit like how top Dukes and Earls saw wiping the King's butt as a seriously good job in the 1400s. Plus, you'd imagine drivers and bodyguards would often overhear and occasionally even see pretty sensitive stuff. If it were me, I think i'd only want the most trusted of my made guys around me day-to-day.
