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"...
I don't know if Paul would have had an easy time taking out Neil.Neil was very well respected and feared by the street guys. Most of them would have rather had Neil as Boss anyway. Paulie had no real hard-core shooters besides Bilotti. His go-to guys were Jimmy Brown,Piney Armone ,Joe N. Gallo,etc. As for the Chin,I don't see any sitting Boss getting involved in an internal Gambino Family war. My opinion,Dellacroce was feared on the street by everyone. He had the whole "blue collar" faction of the Family behind him,and I don't see anyone,not even DeMeo,wanting to mess with him.
