In his book, Al D'Arco mentions that Buddy Luongo and Mike Salerno were the most serious competition for Amuso and Casso.

He also implies that Bruno Facciolo, who was "only" a soldier, was a rare Lucchese guy who had a crew big enough to actually make a move for the leadership. However, D'Arco didn't say that Facciolo had such intentions. But he think it could be the reason why Amuso and Casso had Facciolo killed.

I wonder why Paul Vario was never considered since he was an old time capo with an established crew. Maybe he was in jail at the time.
