I don't know exactly who is taking over or what is going on, but Montagna was not the mastermind behind the killings of the Rizzuto's. He may have played his part, but something much bigger is in play here.
Why do you think Montagna wasn't the main man? Theoretically, the hypothesis of a young crazy ambitious scumbag who thought he was able to take over by killing the older ones seemed to make sense.

2) "Get out of here, old man. Go tell Raymond to go shit in his hat. We're not giving you anything."
