If you get Granlund to play with Malkin and Zucker, it can/could mean getting Geno set up better (because Zucker and Rust both have tunnel vision and Granlund does not). That would be a good thing. But I cannot like a solution where Carter remains 3C and you know Sully isn't really going to play Poehling more than him.
I think this has to be about getting a minute eater who can hold up the third better than Carter, while getting more out of Carter as a RW.

It is better than what we have had, just not to an extent that it is likely to matter in the slightest, and for the playoffs we can call up McGinn again to play with the 4th perhaps. At least Sully will be very tempted to have a PK'er he trusts, and away from Carter he is sometimes a good player, however bland.
For next year it kills the kind of flex we had, or at least makes it even more imperative that we find a way to get Carter to LTIR. A real shame that we have not had any look at Puustinen this season with the big team. If there was any x-factor there to help getting a cheap scorer, it is now likely too late to find out.
