I wouldn't worry about Evander. A lot of North Americans just don't adjust well to playing in the KHL, similarly to europeans showing difficulty adjusting to playing over here.
Vincent Lecavalier, at 24 years old during the last lockout, went and played in russia too. He didn't exactly light it up, with only 7 goals and 15 pts in 30 games. Pretty good article I pulled up from 2005 that talks about some of the challenges a North American might experience in russia.
To Evander owners, don't let this affect his value. I got to watch him up close and personal countless times when he was a Thrasher...and he pushed through to another level last season. He'll be more than fine, trust me. Keep him around, no reason to be alarmed.
