I don't know any other point in Laine's career that he has been basically the best on the team on not only GF% rates (which is not new), but also on relative CF, CA, CF%, FF, FA, FF%, SF, SA, SF%, GF & GA. (5-on-5, this season)
On couple of those he was "only" TOP-2 for the team, but on all the rest I think he was TOP-1 when I checked before the Oilers game from Natural Stat Trick. The irony is, that his excellent Corsi & corsi-type stats are partially due to the fact that he and often his linemates like Johnny or Roslovic have not been able to score on so many excellent scoring chances, which often means they will get another corsi event or two on the same offensive zone time, whereas had they scored on the first grade A chance, their Corsi would be worse while their GF% would be better.
I guess I used like 300 minute TOI cut to not include those with limited sample size, but I don't think the picture was that much different even if you don't filter out any CBJ for this season.
Laine used to ride high GF% often with negative CF%. His scoring touch is a bit off right now, but otherwise his hockey is right now pretty complete, both ends, with still the notable problem being defensive zone defensive play if the opponent is able to keep the puck long on the zone. Laine is pretty good at saving those odd man rushes by opponent, but not that great when the situation gets kind of static on defensive zone.
