Ok..quite possible that Scarfo was demoted because he wanted to take over philly and he had the backing of Amuso( the brooklyn faction of the lucchese). I would think the bronx guys were happy with the way things were and perhaps had some sort of amicable arrangement with philly at the time; why ruin a good thing?
I guess the bronx told amuso to screw off and demoted scarfo jr as a show of good faith to philly( not that they needed too)?
