Yeah it seems to matter a lot more for D-men than forwards.
Also on the subject of Larsson and his corsi numbers. It really isn't surprising why his corsi numbers are poor after re-watching a bunch of NJ games. Their team is atrocious at keeping puck possession in the offensive zone. I thought watching the Oilers the last 5 years trying to create off the rush all the time was bad, but NJ doesn't create much off the rush or control zone time much at all. Their forwards really are very poor at establishing a useful forecheck and even if they do gain possession in the offensive zone their cycle game is quite poor and they often lose possession before they ever have a chance to create anything. Their game seems to revolve around playing a strong defensive game and trying to score off the rush or on the power play when the other team makes a mistake. Most of their games honestly look like how teams play in the final minute of a tied game trying to survive until overtime.
Also one other thing I noticed with Larsson is he actually does try to sneak in from the point quite often, but usually has to turn back because his team loses possession down low. Imo his offensive instincts are there, and while he may not have an elite shot he could easily contribute more in the offensive zone on a team that can gain sustained offensive zone possession and utilize the point (something that McDavid does extremely well, and also something that our team is much more built for with some of the new additions over the last year).
Stats can be deceptive without context:
Corsi is one of the worst offenders in this regard. On another topic

I won't say much other than the following observations: While the rate at which the team gave up ES goals against stayed relatively constant the Larsson/Greene pairing had far better results, particularly last year, in preventing ES goals against than the Greene/Fayne despite the fact that the former pairing seemed to have a much more defensively challenging assignment. This success is sometimes attributed to better goal tending but that does not seem to be the case.
The Fayne/Greene pairing played against a relatively similar group of high quality players but the difference is that many of the top players they played against put up much better numbers against them than they did against Larsson/Greene. This is especially true for the 2015-2016 season.
