For the record, I would love to have Eichel in LA. He's better offensively than anyone we've had since Hart-finalist Kopitar, and before that, probably Ziggy Palffy. But if I'm Los Angeles, I don't trade Quinton Byfield, especially for a player with potential injury concerns. His cap hit is a hard pill to swallow too given that Doughty and Kopitar both have eight-figure cap hits.
I think the best course of action is to find a first line winger, a top four left-handed puck moving defenseman, and a middle six winger.
Guys like Hall, Saad, and Martinez would be interesting UFAs for LA (although I'm certain none of them will be playing for the Kings next season).
