Motivation and linemates have always had a strong effect on Malkin.
He likes to step up when needed, like playoffs or when Crosby is out. But he also gets bummed out like during Covid with empty arenas.
And he loves playing with certain players, but has had trouble with others. That's why he traditionally got the skilled wingers, while Sid made do with whoever else the Pens had.
So he now has nothing to play for, as the team is blowing the season again, and he's with dismal linemates. Pretty clear what the problem is. And it's compounded now by age.
