Ducks did not put Amuso and casso in charge this is such a myth. He put Amuso in charge. Casso was only upp'd to a acting capo when amuso became boss. Amuso was being groomed for the job as far back as the 60s and 70s for the top spot. When amuso became the boss he had a lot of people naturally who wanted the position over him like in any family. Adventually Casso worked his way up to the heirachy but can you blame Vic? The Bronx faction wants his spot and he needs someone to watch his back, why not the most dangerous guy in the family/entire mob...casso. Plus Vic had new and worked with casso and they were both from Brooklyn. Strategically anyone would have done it.
