As far as Sicilian bosses like Gianni Nicchi were concerned, then acting capo Frank Cali was like a boss,to them.

Carmine Galante had outsized power as a capo, I think he bullied Marangelo, who was the underboss.

Scarfo as a soldier, I think rivaled anyone in that family for power back then.

Funzi? I'd put him on the list...


Sonny Red? Him too I guess...


Old school, Frank Coppola, I don't think technically he was ever higher than capo, but when he died he was considered possibly the powerful mobster in Italy..

I think Sonny Franzese has always kinda been considered a threat to the administration, after he got out, I could be wrong though..

Anyone come up with any others?
