I wish Russia was involved too. I think they could do a Europe, Canada, US, Russia tourney if they wanted to keep it to 4 teams. This might actually tip the tables towards the Europeans if Sweden and Finland are together (not sure any other countries would have players lol). They will never do this and just expand it to 5 teams when Russia is back in play.
They could easily expand future “4 Nations like” tourneys and include Russia and a “conglomeration team” consisting of all other countries, they could put out a really good team with Czechia (Pasternak/ Hertl/Necas/Palat), Slovakia (Slafkovsky/Nemec), Germany (Draisaitl/Stutzle/Seider), Austria (Rossi/Kasper), Norway (Zuccy)
Its actually not as easy as you might think it would be to put a full Russia team together…after the top 9 forwards and 4 Defense it gets tough to find good NHLers (they are weak at Center & Defense, but OMG look at their Wings!), they would likely need to dip into the KHL for Khuzzy and Demidov, goalies on the other hand they have 3 or 4 of the best in the World…
