I don't know any players from my country, and I don't know what countries majority of hockey players come from... 2 years ago I thought Barkov is russian, and if I wasn't on hfboards, I'd prpbably still think that way, lol...
There's a joke thread about JT Miller on a main board... I watched him from early Rangers days, and liked him, even when most of fans disliked him, but... don't know what country he comes from. Lucky guess would be from Canada (as most comes from Canada), but if he comes from USA, or another country, it wouldn't surprise me as well.
For me, REAL nationality of players is the team they represent.
