Laine's potential is so much greater than any of those pieces from Anaheim that Columbus would be insane to entertain it. At the same time, given Laine's contract status, giving up anything more is a real gamble. If Columbus wants or needs to trade Laine, they would be best-served allowing teams to speak with him about a contract extension. On a reasonable deal (a few more years at or near his current salary), and on a better team, he's likely worth a lot.
With that said, the best prospect I'd be willing to move for Laine from LA would be Rasmus Kupari, with picks and a roster player or two supplementing the rest of the value. Something like Kempe, Kupari, and a second for an extended Laine. Playing with Kopitar or Danault, two defensive powerhouses, would likely make up for any defensive shortcomings Laine has, plus both centers are excellent passers. He's still young enough that we could pair him with Byfield and/or Vilardi down the line too.
Most LA fans probably disagree with me though!
