That was quick! Ouch. They gave up a lot for him then paid him a ton of money.
To be honest they gave up two failed prospects and a decent roster player. Iafallo is good but LA wanted a scorer. Winnipeg limited their options by demanding roster players over draft capital and prospects.
Iafallo is outscoring Dubois while being better defensively. Kupari is already out of the picture and Vilardi has an injury and honestly paced for like ten points last year after an insane October/November. I don't think he's really a core guy on any team.
Kings have already discovered Dubois isn't good at C. I think the intention was for him to take over Kopitar's slot as he looks to retire in a few years. But at this point Kopitar may stay relevant longer than Dubois. It wouldn't shock me if the guy played til 42, he's been insanely consistent his entire career.
To make things worse, LA have had a very easy schedule thus far. They've lost essentially every game they've played against playoff teams except the Leafs. Largely they've been crapping on teams like San Jose and Philly to boost their numbers. Byfield for example has 2 points in 8 games vs expected playoff teams and 9 in 7 against teams not expected to make the playoffs.
Dubois did also have a very rough beginning in Winnipeg however, he does seem to be slow to adjust. I don't think la would dump him that fast but I feel like LA would like futures more than Winnipeg. They're trying to build a secondary core of young guys to replace their aging guys since most of their prospects busted. They're finishing too high to do that though and Faber seems to be the best one, but they traded him for fiala.
