Gravano said Persico was one of the smartest and respected men in the Mob..His exact quote from Underboss went something like this "but no matter how smart you are sometimes you just cant avoid getting tripped up"that other people were the cause.Gravano also said that Quack Quack had balls but not too much in the brains department.Ruggiero really almost single handily destroyed Cosa Nostra.The ripple effects of those tapes in his house were enormous.Ol Tony Bananna's may have been smart but he may have committed the single dumbest move in mafia history.And his ending was brutal he paid the price
