On the one hand you're preaching to the choir here.
On the other, it's hard to just 'assume' he'd meet or exceed Kakko's PP production, since Kakko was actually excellent on the PP last year.
My personal suspicion is that if Laf had been getting meaningful PP time all season, he wouldn't have a that many PP points, but would probably have more points at even strength and would be playing a lot better since he'd be consistently seeing icetime that positions him to make plays, play with skilled players in the offensive zone, and pick up points more consistently. Confidence is an important element with scorers.
But he's not and hasn't been getting that time. And he's now heading for a 25 point paced season. That's really discouraging. A 90 point, top of his position in the NHL player seems like a pipe dream at this point, whether that's on the player or on the org.
