However, it's been speculated that there is a player being sent down. My guess would be Da Costa, so that would put Konopka in SDC's spot.
You'll probably question my reasoning for putting Filatov on the top line like that. This is his chance. We've seen in pre-season that he is capable of playing at a competitive level. If he is ready, he should be fine.
If Filatov comes in, it's on the 2nd line. Greening's style of play helps free up ice and recover pucks in the offensive zone so that Spezza and Michalek can do what they do best. Not for any lack of skill or anything from Filatov, just Greening is a good compliment to that line.
however I think Foligno, Winchester, DaCosta, and Konopka's spots in this situation are all liable to change be interchanged.
