I've always wondered if Scarfo showed his hand to Phil as he essentially gave him the boss spot, because if so, he must have been jolted somewhat by his choice of Casella as underboss instead of himself, I guess there wasn't really a way for Nick to lose even then because he had about the only thing the Westside really wanted in his grip, which is AC and its unions.
In Leonetti's book they make it seem like choosing Casella did cause a minor disruption in their friendship, but at you mentioned it really mattered not as the Scarfo Crew had AC to themselves and the Testa run was a short one.
