Serp, when Scarfo banished the Merlino brothers. Could they have challenged Scarfo? E.g. If Chuckie refused to step down, he had his crew. But obviously Scarfo took away his power by handing it over to Tommy del... which clipped his wings

But let's just say Chuckie refused to accept it, would his crew along with Laurence's crew/ plus young Joey (Merlino took over not too long after, so he had his young bucks at the time too) mount a defence against Scarfo. And his toughest capo Sal Testa wasn't around for obvious reasons

Scarfo was a maniac but he wasn't bullet proof either. He was usually only with the blade who was in jail by then, his nephew, and walked around with Grande and Milano brothers etc
