It's funny how all this critique on Laine doesn't actually show up in a meaningful way in any stat that measures things that decide games. During regular season he led the team in 5v5 goal differential (+18, Scheifele distant second at +13), in playoffs he was one of the best forwards as well in that respect. Btw. same was true for his rookie season, except that season it was Scheifele leading and Laine distant second (+15 & +9). So no matter what your eyes tell you, his actual on-ice stats continue to be excellent when it comes to scoring goals more than your opposition. After 150+ games in the league, I don't believe that is a coincidence. It's funny how this one-dimensional PP specialist continues to be the best or top-2 5v5 player in his team as far as goal differential goes.
Going off the deep end as far as stats go, his WAR stat for regular season was the best for the Jets (if you believe in that stat), also his Corsica rating (I think another attempt at a stat that combines "everything" to decide who is the best) was 2nd best in the team after Scheifele (practically tied).
I think where this stuff he gets critiqued about actually does show up somewhat is Corsi, which sucked in his rookie season and wasn't that great in his second season either, but here again after 150+ games I think it's safe to say the way Corsi works, a CF for Laine means more than a CA. I didn't attempt to actually calculate this in any way, but quick look at the stats from this season and last, I believe to get to positive goal differential his long-term Corsi doesn't have to be over 50, but something like 46-47 already does it.
I think the bottom line is people would be ecstatic with him if he was getting the results he is getting while looking like he works really hard at it and has 110% effort every shift with dynamic skating and being all over the ice all the time. Instead he does it while looking rather casual a lot of the time and being great at positioning and converting scoring chances.
I think one big reason why it seems mostly Finns who really like his game (beside Laine being a Finn of course) is we actually have a very rich history of players who are strong on their skates and work their ass off every shift of every game and then fail to score when it matters. In other words the biggest shortcoming of Team Finland and Finnish players in general I think has been effectiveness, then along comes a player who gets star player results with his biggest STRENGTH being just that, being effective. I can't emphasize enough how refreshing it is to have the tables turned, to have a player with great results even when he doesn't look that great out there (and who absolutely dominates when he does look good) instead of players who look good but get poor results.
