in the rizzuto/sollecito faction to my knowledge the position of consigliere and underboss do not exist.
boss
street boss
cell leaders
seems to be the administration setup.
the media may be using this term "street boss" but barberio is in fact a cell leader.
OR
with noones knowledge rizzuto and sollecito no longer hold power in the MTL mafia and barberio is now the #2 of the rizzuto/sollecito faction with a new boss?
this second scenario seems unlikely it may be that barberio as a cell leader has taken a more prominent role on the street in dealing with other mafia members,HA and street gangs. these are not roles that rizzuto or sollecito would be taking on.
