If they're just a crew why do they have a boss, consiglieri, etc? It's funny because The Sopranos does go into this. When John Sack tells Phil Leotardo that Tony's a boss, and Phil objects.
It's always interesting to me as to why this family was formed in the first place, when all of the 5 families were always there, the Genovese always being the biggest and strongest in Jersey. Jersey's mob history is fascinating. I'm guessing a lot of guys in the old Newark and Elizabeth families did a lot of big favors for big people at key times in mob history.
