I know that associates get traded around like athletes on draft day. What about made guys?

I know it prolly never happened with any of the big families. It seems to of happened to the families that didn't have the muscle to keep their soldiers with that particular family.

An infamous case was Jimmy "The Weasel" Frattiano. Was this a common thing? Does it still happen? Has it ever happened with the bigger families?

I'm very curious on how easy it is to start a life somewhere else that's mob controlled as a soldier.
