How about Angelo Ruggerio?

Anyone who got tapped, he seemed to end up on the tapes. couldnt keep his mouth shut at all. Got DB killed, even though the guy was no threat to him.

demanded he be underboss, even though he clearly wasnt admin material, then mouths off to the judge who COULDA given him bail, disqualifying him for the position he was making so much noise for, and at the same time time depriving Gotti of a trusted guy on the outside.

Tried to hit Casso, (which was in my opinion, out of his league..) over drugs, (which he was a newcomer to, and not even supposed to be doing..) RIGHT before casso is made underboss, and
he basically has the chins ear, the chief rival of Gotti.

Self proclaimed brokester , i quote, " My brother Sal, he MADE me make money.."

i feel like im forgetting some things, but it seems if it wernt for Gotti and Dellacroce, he woulda been dead, probably never even made. OH i forgot, he wouldnt give up the tapes, so therte is that too....
