If the succession war got bloody, my money would be on Neri.
Did Neri have the brains or just the power though? Mind you I think Neri was a capo so his intelligence must've been held in higher regard than his "predecessor" Luca Brasi.
Not only was he a capo, but he was Mike's right hand man in GFIII before Vincent came on the scene. I'd say Mike thought he had the smarts.
