I don't want to shoot you down Jarka (in fact I'm not sure I am), but off the top of my head, it's not that rare - they are taken every so often, the question remains if 'they're really good' as you say: - Fraser, White, Kruezer, Ottens, Gardiner, Leunberger.
Point taken though. Others such as Minson, Jolly, Cox, Brogan, Hille, Blake, Simmonds, King, who were taken further down the draft or rookied are just as competitive as those taken early.
