wow, oshie seems like a good energy player with skill, and maybe a steal as early as the blues got him but he'd be hard pressed to slip into any gm's top 20 in my opinion, not that i'm an expert.
staal, bourdon, parent, barker, toews, malkin, radulov, rask, tukonen, korpikoski, bergfors, backstrom, kessel, e. johnson, j. johnson, schremp, ryan, frolik, rask, etc. i would take any of these players over oshie no questions asked.
to answer your question though i'd say anybody would have to be crazy not to take malkin at this point. the johnson's are unreal but i've never seen anybody dominate a world junior game like malkin did last night against a very good (albeit tired) usa team.
