AFL team connectivity

With the season over it can be hard for football fans to find something to talk about. Luckily there is the trade period. With trades almost finished I thought it would be interesting to see what this movement of players does to the connectivity of the league. If we assign one link weight to each pair of clubs every time the same player plays a game for both clubs then this is the graph we get…


It makes a lot of sense. The older clubs are the most heavily interconnected. The clubs which joined the original wave of expansion, Adelaide and West Coast are well connected too with Port Adelaide and Fremantle close behind. GWS and the Suns are still not well connected, but they will be soon. The really interesting cases are Brisbane (Bears) and Brisbane (Lions) which are well connected even though they didn’t exist at the same time! The interesting case of Melbourne University is also there. The club only existed in the VFL between 1908 and 1914.

The take home message is that we are all connected!
