Ralphie may have been admired as a good earner, but he wasn't liked. He commanded the respect of his small crew, but how many guys actually liked the guy? It wasn't just Tony that thought of him as a loose cannon. He had a rep. He would never have commanded the loyalty and respect necessary to lead the Family. He also seemed to me to be less street smart and more book smart. He would've been like a hot headed version of Paul Castellano.
