I don’t foresee moving Haula making sense. He’s not so bad or overpaid that you should attach assets to move him.
If you buy him out, the savings is 1.6 million next year and an 800k cap hit the following year. I’m doubtful you find comfortably find a better UFA than Haula at a 1.6 million cap hit.
Moving Palat would be the substantial difference maker. I wonder if the Devils could do something where they retain ~2 million and take back Sheary and Girgensons from Tampa. Net cap savings of 1 million for the Devils next year and both Sheary and Girgensons could be buried in the minors to free up an additional 2 million, if need be. Given the Devils could bury both, I could see the argument for retaining 3 million on Palat too.
