He took over in 2008, so judgement is still out on most of his drafts. I would say 2008 is the only one we can evaluate now.
Eberle was a great pick at 22. Hartikainen would be have been a great value in the 6th round, had he been willing to stick around in NA.
2009 is shaping to be pretty disappointing. Paajarvi is no longer part of the organization--and in either case, it does not look like he will amount to much more than 3rd liner.
Lander etching dangerously close to the bust territory. I expect he's one year away from bolting to Sweden. The rest will never see NHL ice.
2010 could still work out--Marincin is tracking well, Pitlick still has potential to turn into a good bottom 6 forward. Martindale and Hamilton not so much, but Davidsom might continue to surprise.
Over the past few years it looks like we may have picked up as many as 5 useful d-men, but it's been hard to draft forwards. Last two drafts might be looking better, but it's too soon to tell.
