Paul would have stomped Neil out in seconds if it came to war. With one call to his buddy "chin" he would have had all the Westside after Neil too.
Paul couldn't be bothered with loansharking, making book, drugs and violence so why not "give it all" to Neil.
While not unlike others, Gotti and that Bergin Crew were selling huge amounts of heroin and that is against the rules. The jail time for that was something Paul wanted none of. Paul would rule Wall Street, the Garment District and the Construction Industry and read the WSJ every morning.
Do you think if it was stolen car ring that Ruggiero got busted for Paul would have asked for "tapes"...
