How did he “collapsed” crews?
Are you referring to what jonnynonos mentioned about Elmwood Park being absorbed by Cicero?

If he was allowed to do all of what you claim then he wasn’t the only one who wanted to “kill” it. There must have been some sort of a consensus. So I don’t see things changing since the alleged new administration is made by the same guys from DiFronzo’s inner circle: his brother Peter, Salvatore DeLaurentis, D’Amico...

Or people decide to let these geriatrics enjoy their retirement, and started doing things solo, locally, without keeping them involved...save for the weekly envelope.
