Accardo was also said to have been a Capone bodyguard, as was McGurn and Phil D'Andrea.

I hear what you're saying about Chicago's crew system and by now I'm pretty familiar with it and know that it's different than New York (and every other Mob family), but I'm not sure when the crews were set up. Under Capone it might have been one big crew and that they were divided up shortly before he went to prison.
