It's believable that Borgesi is the new boss. Never underestimate the ego. That's what pushes these guys anyway. He just beat the government. He pounded his chest in private, now it's time to do it in public. Of course, I have zero information on this; total speculation.

Now, the original post says Georgie is volatile and has poor relationships on the street; and bodies may start dropping. I will say this: If the Scarfo guys are involved with the Philly Mob and Borgesi is a maniac, hes dead. No way they let another boss send them to jail. And, his friends Mazzone, Merlino(if involved), etc., won't hesitate to blast him either.

If he's boss, he's either in jail or dead in 2 years.

On a side note, the "other shoe" is gonna been when Nicodemo go back to trial/gets convicted/if he flips. All of these guys are on borrowed time.
