There's a gigantic difference between coming over at 16/17 out of MHL than there is coming over at 19/20 out of RSL and KHL.
Those top stars are a poor example, since they all established themselves as solid roster players in RSL/KHL - Kovy, Ovi, Malkin and Radulov are exceptional talents and don't represent an average player at all.
A lot of Russian fans and experts are trying to say exactly that- get established in KHL and ONLY THEN go to NHL for the best chance / roster spot on NHL team (Tarasenko, Orlov). And if you look at Russian NHLers who are solid locks in the lineup these days- most of them have done exactly that.
Only Burmistrov and Kulikov are solid yet relatively average players out of CHL.
Does anyone think he'll follow a similar career path as Kuznetsov or Tarasenko? End up being picked relatively late in the 1st, polish his game for several years in the KHL(amidst rampant although probably baseless speculation he won't come over) only to end up as a top prospect in the league and (hopefully) do very well in the NHL?
