Probably not worth it either to start a small war. He has the number 2 position, makes good money, and knows that the reality is more guys in the family respect him more than Paul. He has the entire blue-collar faction loyal to him. Although he wasn't moved to boss, he still became more powerful after Carlo died.
Makes sense. Many UBs have had more power or were closer to there men then the boss. Why not let boss take all the heat. I have heard many guys weren't happy with Paul and wanted Mr. Neil to get it but Carlo being strategist he was more then likely wanted to insulate Paul, and who better then a stone-cold killer who was loyal as they come to be a buffer between Paul from rest family.
