If the Magpies are a new club then they wouldn't have the same associated clubs registration number they've had for decades, which implies a continuation. Of course Port people went into the AFL, when you promote someone, you need more people to fill the vacant positions. Glenelg didn't suddenly become a new club formed in 1991 when the majority of their people went over to the Crows. It's a specious argument you've come up with. I'm getting sick of a 14 year old child deciding on what the history was when there were people where were not only alive at the time but involved in the process. It's this kind of thing that makes wikipedia a joke.
