Kovalchuk and Radulov had looked better than other our players on Olympics, so I don't even sure if your assumption is technically true.
This is true, these 2 guys in addition to Datsyuk were the top 3 guys there. Maybe that was part of the reason the team did poorly. I think a NT of only KHL guys including Rads and Kovy could compete with the top nations even if NHL guys were included. Call me delusional but it would be interesting to see none the less - Mozy, the SKA line etc.
