not trying to be funny but with players dying directly on the bench with no medical staff around, teams dying in sh!tty airplanes maybe a little bit less players would choose to cross oversea for a little more $$$ than in the NHL.
Your forgetting that for most of the guys, if not all of them that Russia and Europe is home and not overseas. Vasy was playing for his home town team.
Also a lot of them had their time in the NHL and were making a living at the end of their career back where it started. There are very few Ray Emery's. I am sure that if the majorty of them were offered NHL contracts they would have taken them.
