Geelong are interesting on this:
Two sons of a god of their club.
One pretty much went further than the father, the other walked away.
One was driven to succeed, the other decided the pressure and work load were not to his passion and moved away from professional levels.
Did the club help both? Was it the pressure? Or is the personality part of the setup? Did one have more skill than the other?
There are many factors that make up the reason why a son may not be able to follow the father. Some prove to better than their father.
Narrowing it down to the club or not the club is a little trite.
