That's only this season. Up until the Covid break, he was one of the top forwards on Anaheim (not saying much) and led the team in points 2 straight years I think (also not saying much). I (and other Ducks fans) think there is something else going on with him right now, it could be motivation (no fans in the stands and being on a really bad team), it could be out of shape (no hockey for almost a year), or just starting off on a cold streak (he has been a streaky player).
If he's viewed as only a cap dump, the Ducks might be better off waiting for him to hit a hot streak again and trading him for better value when he looks good. He's been extremely consistent over his career up until this year, and with no major injuries through his playing time there is no reason to think that his play should have declined this much this quick.
I guess the short answer is, if he rebounds back to near last year level (offensively and defensively), he's a good 2C. If he gets back to last year's defense and his offense is what it is this year, he's a good 3C.
