While you need good knowledge of the game to become a good FF in the AFL, I think it'd be harder to convert as a ruckman.Don't know, Kurt tippet might be able to help out
I think we shae's athleticism, his verticle leap is awesome he will be groomed as ruck first, but if he has some speed to go with his leap and build he could very well be turned into modern full forward
It's much easier to just mark to ball and kick for goal, than learn to tap effectively, pick up touches around the ground, being accountable for the other ruckman, dropping into the hole down back etc.
I think if he succeeds, it'll be as a KPF, not a ruckman.
