It can be pretty hard at times to determine exactly who is Boss of a family. It seems to me that a few of the families are reverting to power-sharing situations where more then one person holds equal power within a family.

This way, even if one guy goes to jail, there is not suddenly a power vacuum, as there are still others to control things.

This may be the case with the Gambinos (Squiteri, J. Corozzo, N. Corozzo) and the Genoveses (Gigante, Cirillo, Magano, Bellomo). Im not sure about the other 3.
