I think the Kings can improve significantly just by being healthy.
The link below indicates there was a big difference between Quick and Budaj. The failed Muzzin/Martinez pairing is not going to be repeated. Going into last season Forbort, LaDue, and Gravel were all rookies and the kings had to play a project in McNabb that had barely 3 seasons worth of games played.
the other members of the defense aren't question marks any more. Forbort exceeded expectations. Folin from what Wild fans say has top 4 potential. Fantenberg provides added depth and Gravel is no longer a rookie. We aren't going to pair Muzzin and Martinez together - at least we shouldn't.
I can see 15 goals fewer in GA. the link indicates 10 is reasonable from getting Quick back alone.
Bounce back seasons for kopitar and toffoli would help. Kopitar averaged 24 goals. I'm hoping for 20. And 25 from Toffoli. That's 17 more right there.
So I think 215-220 GF is doable. I have seen a number of other posters here expect a lot more GF. NHL average last season was 227. So still below average. But add in the GA reduction and the goal GF/GA differential could be in the 30s even with a significantly below average offense. That's a solid #3 or even #2 division team.
Key Kings GF stats
2012 GF 188
2014 GF 198
2017 GF 199
The kings can weather a well below average offense. The question becomes is the defense good enough. the average GF/GA for a division winner last season was +40 - and that includes the Caps insane not to be repeated numbers.

THe stats and below average offense were with Sutter's system, not Stevens.
GF over the last 5 seasons - 2.6
GA over the last 5 seasons - 2.3
That left little room for error (props to Quick) and that will change, with more scoring ops with the new system.
They will score more and be a more exciting team to watch and I think will be better, as far as players producing.
But those Key stats you used above, were based on Sutter's defense, not STevens. And even though those players are trained under Sutter, there will be differences that will affect the zone time, SOG's and goals for the opposition. I like their young d but do expect sophomore-itis that hits a lot of players in the 2nd year. And they are adjusting to a new system. I see them in the 225 goal range per team, but I also see a spike in the GA with a new system that will deploy and use the players differently in some areas.
I think TT will be in the low 30's as far as goals, Carter, Pearson and Kopi are in the 25 ea range.
Also, the competition, league wide, is better and there are no more gimme games, with the current playoff structure. Most teams fight a little harder for those 2 pts. There is a boatload of young talent around the league which is going to become the norm, due to the CAP. Right now, the Kings (doughty aside) have an aging core.
They need to get off to a great start, bank some points, and hopefully adjusting to a new system , with them familiar with the coach, won't be as long as it takes normally.
And JQ should have a good year.
I think the Pearson, TT, LaDue, Gravel, and co, the young top players coming up and Vilardi and such in the next few years, will be a very solid path forward for the team
