Think the only thing for sure is Merlino is the boss and Grande and Licata are capos. Steve Mazzone could be underboss or he could still be consigliere. Lance, Marty Angelina and Johnny Chang could be captains. Iannarella could have a position. Borgesi could be a player, or he could be off the totem pole. Ligambi might be retired fully.
Last reliable estimate was four or five captains in total and about a dozen active soldiers.
