Firstly, you don't even know what type of player McGovern is, and what he can do, do you? Only Himmelberg and he are playing the same role. If you'd mentioned Walker, Jenkins, Fogarty and Himmelberg you'd be a lot closer.
Whether I have any idea or not what type of player MM is, thank you for agreeing with my point that the Crows have plenty of back-up in what he can serve up.
Also, I'm 99.9% certain McGovern will be a better player than McAdam. Already has a 50 game headstart and a decent highlight reel.
Sure, the second rounder allows for the risk that McAdam will not be as good as MM long term. But whatever the value of your 99.9% certainty (would that footy - or life - could provide such certainties) if the Crows want McAdam, and it seems they do, then presumably it is because it is thought McAdam has some prospects of being a decent AFL footballer. No?
