I heard in the past although families may have had less capos, the crews were massive, far bigger than today.
I'd figure it'd be harder for captains to keep a tight hold on their crews with more soldiers per crew. Though it seems less like a heirarchial structure with bigger crews; soldiers can go to the bosses easier.
