We can speculate on Sal all we want. Look at who replaced him when he was deported Vinny TV. I think that guy was easier to control or use as a acting boss then Sal. It clearly shows Sal was a rising star in the family and was not to be used as a front like Fat Tony Salerno was. Lastly, he had to be capable for he lasted, what 3 years as acting boss. He did serve under some great captains (Sciascia, DeFilippo, and Basciano). We need more rats from that family during that time period to fill us in about Sal's short reign lol.
