You also pushed the 7 million people watched AFLW lie from the AFL, so I don't believe anything you peddle.There are at least 442 (81.1%) on a current list who played football formally growing up (either in juniors, or as teenagers playing seniors). There are also 33 (6.1%) from Ireland.
545 list spots this season leaves, at most, 70 others (12.8%) who either didn't play it growing up, or I can't verify they did. Happy to just say all 70 didn't, hell of a lot more accurate than "half the league".
