I think the bigger picture rather than looking at just last season is important--Kings sure had some phenomenal seasons last year that are hard to duplicate, yet they still dealt with a major injury, and they ended up with 98 points. Previous year was the real bad one with 86. Prior to that? 102, 95, 100, 59-on-pace-for-100, and again 95. They seem very consistent from year to year despite those injuries and performances so I think it's ok to suggest they'll end up nearby even without the duplication of those guys and whether things go perfectly or not. Which is why the part Im most interested in is can these guys be healthy for the playoffs and how can they squeeze another 5 points in throughout the season...and as long as Kopitar/Doughty are healthy, we should be fine. The additions of Kovalchuk and (theoretically) vilardi/rookie x should be enough to 'keep pace' if not improve like other teams have.
If anything, 2017 was the outlier, as from 2012 till now, the Kings have been a 95-102 point team.
