Difficult to say. I remember I saw somewhere a structure diagram. Then the Don was linked to Underboss and Consiglieri. But the Underbosses were linked to other people and the Consiglieri not(just an advisor as in the business). But when this is true it's strange that the Consiglieri can give direct orders, so I think the structure should be Don=>Consiglieri=>Underbosses.

We wait for Turnbull
