My father and uncle (two VERY knowledgable guys - in the life), told me that Tommy Brown was THEE best boss (bar none) around in his era
Interesting, is that from an earner's perspective? Lucchese's did a great job until Corallo turned things over to Amuso after Casso turned him down.
Knowing how Tommy became boss, and reading Joe Bonnano's book, it seems Tommy was smartest by not being a thorn in anyone's side. When you read about Tommy and Joe having a private conversation about the Anastasia/Costello stuff going on, Tommy reveals it was Vito Genovese guiding a lot of his moves. Seems like Tommy was really good at not reaching for too much and sharing with others, specifically Carlo Gambino and Vito Genovese.
