I look forward to your critical analysis detailing exactly how McCartney under developed those players directly through his actions and what Beveridge did directly through his actions to counter that.
I am not going to go through every player. I will give you one example and not from a young draftee either.

Played back pocket or a tagging role under Macca. Was instructed to beat his man and sit on that player. One day, ran forward to make his man Harvey chase him and kicked a goal. Was immediately dragged to the bench for a word and he never left Harvey's side for the rest of the match.
Under Bevo, he plays as an attacking high half-forward role. Flies for some awesome marks and kicked some hugely important goals in the finals series.
Macca was good at teaching players to win their own ball and not be afraid of contact. But his strategy and lack of inspiration made it hard to watch the dogs play.
