That depends on what you think he is. He's an above average goalie who gets a lot of starts. He's had a couple pretty bad years, a couple very good years, and mostly solid years. He's agoalie that should have good value in your league. You have 4 of the roughly top 15 consensus goalies, and having 3 is plenty.
"LA is going to be a bad team for years" is both irrelevant and likely wrong. He's not a keeper for you, so only this year matters as far as the Kings go. I checked to make sure I wasn't crazy, and the Kings are leading their division. Leading your division means you aren't a bad team by definition when your division is as large as a NHL division, and it's the modern era.
Figure out which 1-2 you want to keep, shop the others, and trade one for the return you like best.
