I don't think there's any way we're not using excess capital and picks for a trade. More likely in the off-season. There's no way a guy drafted 26th overall is going to come to help the team when Cole/Nick/Dach are in their prime unless we get lucky and another COVID comes and nobody can scout Wyatt Johnston again.
Nobody else from 2021 onwards is playing in the NHL except Johnston. Even in 2020 Chinakov is probably the best guy drafted after 20 but he was an overager. Even 2019 guys drafted that late are still clawing to get into the league. From 2018 Veleno is just taking a real full time top nine role now five years later.
I would expect some struggling 2019-2021 prospects, or decent players on teams trying to tank, ala Dach, to be targeted.
For lower/medium cost guys, potentially Holloway, Lundell, Bourque, Cuylle, Kakko, Kaliyev, Holtz
Higher cost Zegras, Lafreniere, Nikishin if he refuses to sign in a dump like Raleigh, or Zary. Turcotte outside chance as he's starting to put it together a little and LA need cheap players badly.
Probably Zegras is the only "elite skill" guy available. I would bet on Turcotte or Zegras as the target though, as both can play center or wing and have experience playing with Cole. Allowing Dach/Slaf/Newhook or someone better to complete the second line. Or even doing Cole/Dach/one of the US guys and Slaf-Nick-Newhook as the second line.
