The standard, what ice surface are they playing on question?
NHL - NA Team
IIHF/Olympic - European team
Would be fun to watch and close games, but that is kind of how I see it.
Would take Doughty over Letang.
But you can get into a lot of team fit arguments and your own lineups. Just cannot see taking Letang over Doughty, especially with PK and Keith to play slick PMD roles and Doughty providing offense and far superior defense to Letang.
Some of these Russian players you listed are from Asia. As well I noticed you listed Ovechkin as RW on line 1 for Team Europe, but failed to list him as LW on line 2 for Team Europe, any reason behind this?
