I would keep Samsonov, he will play with Toews maybe.

Ruslan Fedotenko is currently in the top ten in scoring with five points in three games thanks to a great start by Mike Comrie. But this is a guy who has not scored more than 41 points in a season in 6 full NHL seasons despite playing with the likes Brad Richards at his side and sharing ice time with Vincent Lecavalier and Martin St-Louis. So yeah, ride him while he’s hot, but don’t count on him to help you out all season.
