You are right, I should have mentioned CHL as a potentially useful production line, but my post already was miles long and I like to not be fired from my job for neglecting it while I polish my essay on Belarus youth hockey.
In couple of years we will see what comes of this, because we don't have enough data for it to be called as a surefire success. What I disagree is that there is some sort of a programme shift that has taken place internally in Belarus. CHL was not drafting Belarussians because there was almost nobody worthy of a draft. First came the talent only then CHL realized that there's gold that can be mined so to speak and started taking them in bunches.
