Classic Dubas sort of "depth filler" signing. Smallish "tweener" guy who isn't extra terrible at anything, but also completely lacks any sort of defined role. Who will frustrate and disappoint in the Top-6 because he's not skilled enough and wildly inconsistent and streaky in every aspect of his offensive skillset, and not a great finisher in the first place. But who will also just disappear into the woodwork in the Bottom-6 because he doesn't play a physical or remotely impactful game there in any way either, totally ineffectual on the forecheck, nor is he a PK specialist or shutdown player or anything of the sort.
But hey...$1.25M for a year is pretty much what that sort of underwhelming blunted Swiss Army Knife is probably about worth. It's basically no-risk, extremely marginal reward.
But pretty much guaranteed at some point he'll have Penguins fans screaming and pulling their hair out watching him flub plays from Malkin or Crosby every time he touches the ice.
