Give me couturier, very close though... Yakupov has much higher ceiling while I see couturier being a winner, like a Bergeron type do it all player. Yak has more bust potential. And like you said, you unil teams around centers.
If you want to use absolute ceilings then Yakupovs is that of a 50 goal scorer and I take a 50 goal scorer over the player you just described.
If yakupov has 50 goal potential, then couturier has a significantly higher offensive ceiling than 60-70 points, IMO.
I'll take Couturier because of his superior two-way play. I also think he is better suited to making his teammates better. Yakupov is incredibly dynamic, but from the little I've seen(highlights and WJC), he's a bit of a one-man band.
I expect him to be Kovalchuk-lite, while Couturier will be Jordan Staal-lite.
hmm I feel Couturier will certainly pass Jordan Staal.. Let alone a Staal-Lite.... Lol I see him more like an Eric/Jordan mix... May not be quite as good defensively as Jordan but it will be close and not quite as good as Eric offensively but close
