You miss my point. There are great Finnish players, absolutely. But how many Finns are drafted versus Canadians? If we took 5th round Canadian he is maybe 100th best Canadian in draft. If we took 5th round Finn he is maybe 10th or 15th best Finn in draft. So 5th round Finn has much better chance to make WJC. If we took 5th round Swiss he might be 3rd or 4th best Swiss in draft. Absolutely would make WJC.
Would we get better players if we drafted more Europeans? Maybe. I don't know. I do think they tend to be harder to scout because top ones often play limited minutes on adult teams, which can mean you do get some hidden gems and is likely worth a shot in later rounds. But regardless of whether we get better NHL players by drafting more Euros, we would absolutely get more WJC players.
