So what? The concept still relies on it being anchored in reality.
The AA selectors have put Joe Daniher and Tom Lynch in a forward pocket. If the selectors can put players out of position into the team, how come they can't select two ruckmen, especially given the ruckmen they'd be picking from could easily play tandem and push forward?
Your basic argument is that the team should function how teams and players play/represent how teams pick players. When was the last time you saw Daniher in a forward pocket? And don't give me this "oh but he's a third tall in the team nonsense" firstly, Daniher never plays as a third tall or linkman or forward pocket or any other type of forward, always takes central position in FF or CHF. Secondly, how many teams play with three KPFs, like Daniher, Kennedy and Franklin? Richmond sure don't, neither do Melbourne, Hawthorn, GWS, Geelong, Collingwood, Sydney and a host of other sides. Some do, like Adelaide and West Coast. But many don't.
Now
why don't they? Partly due to the faster nature of the game, but also, it's hard to find three genuinely good tall forwards these days. There's a reason why Richmond are chasing Lynch, it's because Richmond
want to play a second tall but don't have anyone worthy of selection.
But if the AA panel see three talls worthy of selection, I don't see the problem. I think Daniher could play as a third tall, it's not as if he
can't play the role, it's just that due to the limitations of Essendon's list, he takes on a different role. So if we can have three genuine KPFs who can admittedly can move around the ground and be flexible, why can't we have two ruckmen who can do the same? You don't even have to have them on the field, pick the best ruckmen in the ruckmen position then put the next best on the bench. Because at the moment, Grundy and Gawn are in AA form and Naitanui isn't far behind once he improves his fitness base.
And if you tell me that Franklin isn't a real CHF even though he was selected at CHF then it just proves that these rules about selection are silly.
