There are no good options at 2C, but three better ones than Luke Johnson so I'll call it progress. I'll vote for keeping Rask on the 4th line, where he's been mostly good, and away from the 2nd, where he's looked lost. Ek and Sturm bring roughly the same things, but Ek has more experience at this level so I get letting him have the spot that neither player is suited for. They could flip Sturm and Rask, but I don't see the point.
I'd rather see Parise back with Fiala and see what Donato can do with Staal and Zuccarello, but I don't think it matters enough to get bent out of shape about.
