Rare Jewel
Patience
I don't want to rag on Bozak, it's been done to death and the guy gives us what he's capable of but I still maintain Marner needs that defensively dogging type center (like a J. Stall, Couturier, Dubinsky).
Matthews
Kadri
Solid defensive center
4th PKing center
I'd agree it has been beaten to death, but the Bozak/JVR thing is a mess.
For me it's one or the other (Keep JVR for me due to the goals), then you add another centre like you mentioned.
