Let's use Jack Gunston as an example. He was a late 20s pick for the Crows in 2009 and played 14 games in his two years with us. He was very quickly showing that he was going to be a gun forward, and hence attracted the attention of Hawthorn. He rejected a lucrative contract offer from the Crows and demanded a trade to Hawthorn. We ended up getting pick 24 and an upgrade on a couple of later picks. Basically we got stitched up.
Yes, Scharenburg was a higher draft pick, but his injury has curtailed his development and poses serious questions marks about whether he'll ever reach the heights that were originally predicted for him.
He's worth somewhere between pick 15 and 25 now I'd think.
