This is an interesting topic. there is no question Neil was a throwback gangsters a man who was both feared an respected on the street. neil would have been a great boss in the 50/60's but by the time Carlo died the blue collar crimes were starting to die down and the white collar crimes were the future. Now Neil would have been a good candidate but he was under investigation a lot. Carlo saw Paul as someone like he was in regards to white collar crimes. Also Paul wasn't under investigation like neil was. Now im not praising Paul because like others said he was greedy and reclusive. But Paul was a smart guy and i think he could have been a good boss if he kept a little closer eye to the streets maybe he would have been more respected
