We'll put all the resources and development into Draper, then he'll go to another club.
That's the way Ruckmans work. Clubs trade in their ruckman. its like Goal Keepers in soccer. There is only one position available. So if there isn't an opportunity, they'll walk to a club where there is.
IMO all clubs need to re-invent the way they develop Ruckman. When they first arrive at the club as an 18 year old, they should learn how to play key forward. Then when they reach 22-24 start working with them on their ruckwork. By this stage they've built a ruckman's body, and have a few preseasons under the belt, and also have a feel for the game. Hopefully they've outgrown their 'clumsy'.
