This would just be poor roster construction. Can’t really bank on Spence and Clarke to be horses come playoff time, plus LA doesn't even really need Tarasenko.

I don’t think it’s necessary to have Tarasenko.
LA has talented young players in their roster.
I’m just saying.

Amen. LA's offense is among the top 5 in the League, so Tarasenko is a luxury. Matt Roy, on the other hand, is a necessity -- putting a rookie defenseman on the ice at the beginning of the season is one thing, but asking Brandt Clarke to step in for the last 20 games and then hold down a starting spot in the playoffs is a recipe for early discouragement.

So can you guarantee injuries won’t occur? What if Fiala or Kempe get injured? Spence has played enough NHL games and personally I like Spence more than Roy. I have an official source that Roy will not remain in LA after this season. Clarke can handle being a 3rd pair defenseman. Also Matt Roy is having his worst season as a King. Tarasenko will have more of an impact than Roy. I know you’re a huge Roy fan but in reality you don’t keep players just because you’re a fan of him. If Roy was to be injured for rest of the season, I can guarantee you it would make 0 impact.
