Err, Sens made that policy because of the Russian flight risk and being burned one too many times as a result.
Yeah right this isn't 1995, there are many Russians that have came over to play in the CHL and have said they wanted to stay here. There is a higher risk that your NCAA drafted prospect leaves your organisation and joins another then for a Russian to go back to a weak KHL league.
Especially with the shitty health of the KHL, a lot more KHLers are looking to move to come back.
