My rationale with Claesson was that he's a fine 6/7 and that's something of value until he is actually forced out by a kid. Not just forced out on paper. And when that happens you waive him and he's either claimed or goes to Hartford.
The other scenario is maybe you find a team desperate for a guy to plug into their 5/6 spot with some experience and some upside, and you get a sixth or a seventh. I know it seems mostly unlikely with Claesson but who would have thought that Mazanec, who was not even close to as good at his job as Claesson is at his, would return a seventh? It's good to have as many cheap assets as possible, because they always have the potential, slim as it may be, to become something else. That's why I think they should and will keep Claesson.
Bergman, it's just a matter of there's really no reason not to qualify him. He won't sign so I don't think he'd count against the 50 limit since he's not actually under contract, and the 90 reserve limit is irrelevant as no team ever gets even close to that number.
I don't actually think Bergman will ever play in the NHL, but he was once a very promising prospect. If we can retain his rights for essentially nothing, why give them up? I mean, we could have renounced the rights to Pashnin (different mechanism since he's in the KHL, but same situation) but we've held onto them, and now he's 30. We did that with Ilya Gorokhov until he was like 32 or something. We'll keep Jensen's rights until we no longer can because we don't want him signing with another NHL team. There's just no reason to let a guy like Bergman, who may still have potential, enter UFA status if we can retain his rights. I would assume the Rangers planned for this when acquiring him, otherwise his inclusion in the deal would have been truly pointless.
