I've always been doubtful about him being the underboss as well. Over the last few years, the immediate rankings below Ligambi haven't seem to be 100%. One source will a certain guy is in this position, than the next year you'll hear somebody else is. Beyond that, he doesn't seem like the kind of guy Ligambi would want as his #2. It seems Ligambi depends more on Staino and Lancelotti anyway.
