Historically:
USSR - Brazil, because: beautiful skilled hockey way back when
Canada - Germany or perhaps the “Flying Magyar” Hungarian national team of the 1950s
Sweden - Netherlands (total football, nice and skilled and usually very competitive but ultimately falls short)
Russia - Côte d’Ivoire (Like y’know when they were the most fun national team to play in Fifa, with Yaya Touré and that fun, fast, deep and skilled trio of forwards? But then fails to win at the World Cup with those awesome players)
Finland - Ranging from Drillo Norway or 2004 Greece, to Italy
Czech Republic - Really liked
@karhukissa likening them to Portugal. Jagr and Hasek were able to carry them kind of like Eusebio, Cristiano or Figo did, I guess.
Slovakia - Belgium perhaps, with their respective great generations that probably deserved better fates, but all things considered had their finer moments.
Switzerland - I’m thinking like, Poland, with Josi being Lewandowski, but the team overall having been quite competent for a while now.
Slovenia - Northern Ireland with Kopitar = George Best.
USA - Spain, maybe? They were always one of the hockey nations and had a great league, but their national teams rarely put it together until 2010/1996. Or like, Denmark, with the 1996 World Cup and 1992 Euros, or that fun 1986 team, and a pretty impressive side over the last few years that crumbled at the World Cup (like Team USA in Nagano, perhaps!)
Czechoslovakia - Czechoslovakia? Haha, I don’t know, maybe Netherlands again
