So I am rewatching The Sopranos, one thing that comes up by some fans is that Tony was very disrespectful of New York and certain things would not happen in real life. In my opinion, I know the ending was completely unrealistic as far as the war but James Gandolfini's potrayal was spot on.

He first treated Carmine Sr. with alot of respect equivalent to dealing with a Tony Ducks. or a Tony Salerno.
He treated Johnny Sack as a personal friend who he learned at the end of the day, it was about his insecurities and money. He treated him like a underboss/Acting Boss but not with the reverence of Carmine Sr. He remained constant with Carmine jr., Rusty Milio, Doc Santoro because they were transitional powers equivalent to Top Capo/Administration. Tony and Phil had several beef in the series it was more personal but he gave Phil almost as much as Johnny Sack

Tony never really gotten out of line until the Coco situation. That was definitely too far and outta line. Other than that He remained cordial and constant in his position in regard to doing business with NY and maintain authority in Jersey.

David Chase, the show's creator, said the Sopranos were based on the Boiardo crew. That's Westside. So, it's no wonder Tony had the nerve to push back on NY. He's based on a captain in a NY family.

So it's based on an NYC crew, not that jersey crew...Vinnie ocean wasn't it?

I think season 1 had to have been based on the DeCavs, especially with Jackie dying of cancer and the power struggle to replace him. That was just about a reenactment of the DeCavs in the 90's. But David Chase said they're based on the Boiardos. I think he meant overall, as to the style of crew they were. There were a lot of writers on this show and who knows what kinds of consultants were hanging around to give them pointers. I know there was also some article around the time the show came out where these cops that cover both north and south Jersey were identifying Jersey and Phily mobsters that most resembled the characters in the show and one said that Tony had to have been based on Michael Tacetta because he was the only mobster around that time that made his way around Jersey with the kind of boisterous swagger Tony did.

Today is actually the anniversary of the first airing of The Series.
