Licata discussed this with John Gambino on the Stefanelli tapes in 2010. Says it's about quality, not quantity. A lot of the guys who were identified as being made in the past 20 or so years are also blood relations or guys who have been around all their lives (to reduce the chances of them flipping). Phil Ligambi, Anthony Staino, Frank DePasquale, Al Lancellotti, Marty Curro, Sam Piccolo, Dom Grande, Sonny Mazzone... all have close relatives who were made before them.
