Probably nothing, but my one question is this: How much better are their players that get picked 25-55 and end up being the Nadeau, Howe, Cataford, Pinelli or take your pick of some crappy 19 year old from Canada's team this year that didn't do their job well, than those players on the other nations? You have players on some of these other teams that aren't even getting drafted or are re-draft guys or late round picks, and they seem to not perform so much worse than the Canadian players that would virtually all have some of the highest pedigree if they played for these other nations.
It makes you question if some of these Canadian players are overrated for their draft pedigree. Are they getting overdrafted? Maybe not. I don't see a widespread reason to believe so. If anything, some of these other countries might see their players a little under-drafted (Czechia, Finland, Slovakia, Switzerland, etc, even to a lesser extent USA, Sweden, and Russia). And I guess a byproduct of that may make the Canadians slightly over-drafted when you factor in a correction for those other nations, but I think there might be something to that NHL teams are a little too insular and there might see some benefit from recognizing the game is going more global and some of these nations that can't compete with Canada for draft picks really aren't as much worse as the NHL draft indicates and maybe the correction needed is with NHL teams when they make their draft selections.
