Keep in mind that Castellano's elevation of Bilotti to underboss and heir-apparent was one of Big Paul's biggest mistakes, and one of the major reasons Gotti was able to get the other Gambino captains (and most of the other big players in the NYC Families) on his side. If Bilotti had not been killed with Castellano, he might have claimed the Donship,but he never would have been supported by anyone.
