castellano made more mistakes than most as a mob boss , he was disrespecting his wife he was far to aloof and he thought he was better than the blue collar faction , he let the genovese family whack a gambino soldier in Connecticut and he let his house be bugged ( just like gotti) . He made a big mistake letting Neil dellacroce basically run the blue collar wing splitting the family into two factions , people like gotti thought castellano was handed the position as boss without earning it which was bang on the money . Castellano was a businessman not a mobster and no doubt he would have been a success in the legitimate world , to say that he didn't make mistakes and lay the blame for everything that's wrong with the American mob at gottis door is deluded , yeah he made mistakes but so does every mob boss , castellano included FACT
