John Stanfa was close to the Cherryhill Gambinos, John and Salvatore, it was them that help to protect Stanfa, Gotti didn't have nothing to do with any of that except to support Stanfa has boss of Philadelphia. I can just imagine how Nicky Scarfo felt about that while he's in prison.
Wasn't Bruno closed with the Cherry Hill Gambinos too? He didn't let his Phily guys peddle dope in Phila's territory but he allowed the Gambinos and got himself a cut. Why would they back the guy who drove Bruno to his death. The Gambinos must have been happy making money being the only suppliers in Philly and having a tight relation with Bruno.
