My take on what he said about Bufalino family;

- sammy misunderstood the movie. Not at any point did the movie say that Bufalino was boss of philly just that he was close to Bruno. If you remember the arson scene Bruno it was all Bruno’s decision but Bruno said Bufalino helped you etc.

- the movie is 3 hours long and ain’t goodfellas type. Sammy is probably an impatient older man and muddled it up.

- sammy doesn’t dispute they’re a proper family just rambles about Bufalino really and says multiple things either way
