I understand where you are coming from, I was one of the fans who wanted the Kings to suck in 2022 and 2023 so they could reload the system and actually draft some guys who might project as stars (especially with how strong the 2023 draft is probably going to be). Right now I feel like Clarke is the only young piece who really projects as a potential star caliber player that could win hardware one day.
But once they made the commitment to trying to win quickly again with one more kick at the can with 11 & 8, and with the struggles of Byfield and Turcotte to live up to the draft capital used on them and Vilardi's inability to play C at the NHL level they had to address the center situation for Kopitar's final few years in the league. And I think the added bonus is that PLD at least has a chance to maybe take another step and even become the teams best C as early as this season, and he's young enough where if the Kings do have to rebuild when 11 and 8 retire he can either be the teams temporary 1C until they draft another one, or he can be flipped to a contender if the Kings go scorched Earth in 3 years.
And yes it's in the realm of possibility that Vilardi takes a big step too, but it's also in the realm of possibility that everything went right for Vilardi last year and he regresses back to what he looked like his first couple of years in the league. At 24 years old, I just don't think he was young enough or impactful enough to keep him as winger, when you had a gaping hole at 2C and a much more proven player only a year older than Gabe available.
