if they last team to do it was in the 90's 20 years ago its not a common thing?
In the '90s, there was no professional hockey in Russia, just some government-sponsored teams, one or two of which might have better than any team in the NHL, at the time, so guys like Fedorov, Mogilny, Kasatonov, Bure, etc. came over to pay their first games of professional hockey. The Caps signed some old guys like Tatarinov who could barely play much anymore because you could get free NHL quality players.
Some time around 2000, the Russian Super League formed and made a point of hiring as many Russian-born players as they could afford, overpaying rank and file NHL guys to bring them home and develop the sport. NHL teams mostly stopped scouting any Russians they didn't think would be superstars, because guys were leaving whether or not they were finished with their contracts.
The KHL, which replaced the RSL, hasn't been blessed with quite as much financial stability. A couple teams have bounced paychecks, or gone bankrupt. NHL lockouts sent a bunch of NHL guys over to Europe to play, and made the cultural barrier seem less daunting. Now ordinary players from each side of the pond are playing in any league in Europe or North america that gives them a contract.
Of course, Orlov and Alexeyev are better than "ordinary," but just as a general trend, I think diversity is increasing in the NHL, and abroad, and that can only be good for sports, and for international relationships.
