It's funny, like Gotti was terrible at business, terrible at hits, (the bar hit, the 3 capos burial, ect..) cocky, vain all that, but just looking at how he handled the hit on Paul, the reaching out to the families back door like, the moves to control the commission, how he was able to read Chin, (actually he seemed really good at reading people in general) and indeed shamelessly lie to his face, And just how he handled himself in sit downs, I think he would have made a good consigliere, a politician, someone you send to deal with other families.
A tough negotiator, shrewd, great understanding of Cosa NOstra treachery, only thing is he still would be too damn visible...
