The influx started a little earlier than that (I'd say the 2013 draft was the start), but how many of those older guys in the top 10 in 2017/18 were playing with youngsters that were much better than the guys they replaced in the depth chart? Crosby had Guentzel. Wheeler had Laine and Ehlers and Connor. Giroux had Provorov, Gostisbehere, Konecny.
For the younger guys, McDavid had Draisaitl. Kucherov had Point and Sergachev, not to mention Stamkos. Mackinnon had Rantanen. Hall played with Hischier and Bratt.
The few guys who buck the trend of playing with talented youth were Malkin/Kessel, who played together, and Kopitar with Dustin Brown.
Obivously, all of that youth wasn't ready for prime time yet, but it was starting to help drive scoring up. As those guys progressed, and more talent joined along side them and progressed, a lot more guys are playing with good young linemates and scoring more as a result.
There was also a massive lull in drafted superstar forwards after 1991 that ran up until Crosby/Malkin/OV at the lockout, and then another one after those two drafts. It wasn't until about 2013 that we started regularly seeing high talent guys coming through the draft again for about a decade, and seem to be heading for another lull. Hopefully, it doesn't last 20+ years this time and we aren't destined for another low scoring era starting in 12 or 15 years.

Yes, 48 point Guentzel in 2017-2018 is what Crosby needed to start scoring more. Letang, Malkin, Kessel and co were not good enough. 0 evidence that Guentzel had an impact on Crosby that season. If anything, they both benefited from league wide scoring going up.
Wheeler - in 2016-2017 the Jets had 82 point Sheifele, 64 point Laine, and 64 point Ehlers. In 2017-2018 Laine was stagnant and had only 6 more points in 9 more GP, Ehlers had less points, Scheifele had less points. 0 evidence that the young top-6ers had any impact on Wheeler
Giroux - Konecny went from 28 points in 70 games to 47 points in 81 games - not even close to a difference maker. Provorov went from 30 points to 41 points. Gostisbehere did go from 39 points to 65 points from 2017 to 2018, but he also had 46 in 64 in 2015-2016, and dipped back to 37 points in 2019. Once again, no evidence that hugely talented young guys are what contributed to Giroux resurging in 2018 and 2019 when scoring shot up league-wide.
McDavid - Draisaitl went from 77 points in 2017 to 70 points in 2018. Once again 0 evidence that Draisaitl supported McDavids point growth. Also too hard to mix up league-scoring increases and the increase that comes from 20 year olds simply developing.
"For the younger guys, McDavid had Draisaitl. Kucherov had Point and Sergachev, not to mention Stamkos. Mackinnon had Rantanen. Hall played with Hischier and Bratt."
Kucherov - Sergachev was given a big role and had 40 points (pretty spot on for any teams #2 offensive D), but dropped down to low 30's for like 4 years after that. Stamkos was healthy again, but also saw a huge increase in performance from the few years prior (in-line with the statistical increase in league-wide scoring). Point did get a good bit better, but I think the fact that having healthy stamkos, and smaller goalie pads and higher league-wide scoring is a lot more representative of the change in Kuch's scoring than simply better young guys.
Mackinnon and Rantanen and Landeskog - They all doubled in points, that's really just high-talent guys that were super young and took a big step forward. Has little to do with changing the league-wide scoring, as all young teams will have breakout years where their young stars get better. Seguin went from 22 points to 67 in one year. Either way, this is not a good argument for my explanation since all of those guys on that team got better, and doesn't impact all of the older guys that all started scoring more when scoring went up.
Hall - Bratt had 35 points in 2018 LOL. Hischier did come in and put up 52 points, but pretty crappy argument if you are correlating a 52 point kid being the reason why Hall put up 93 and paced for 100 points.
"Obivously, all of that youth wasn't ready for prime time yet, but it was starting to help drive scoring up. As those guys progressed, and more talent joined along side them and progressed, a lot more guys are playing with good young linemates and scoring more as a result."
Under your assumption, was it
only youth forwards that were good talent?
You are assuming that:
-> Forwards got better
-> Defense and goalies stayed the same
And this is what resulted in higher scoring. Is your argument actually just counter-intuitive? If you are saying that better teammates resulted in higher scoring league-wide, isn't 50 goals in 2015 with lower league scoring and lower quality team mates (ie. less help) just as impressive as 55-60 goals in 2024 where you have better team mates and more help (ie. an easier time scoring goals?) How do you then separate individual performance vs. how much your teammates are helping you out.
For example, Wheeler finished 11th in points in 2017 with 74 points, and 9th in points in 2018 with 91 points. Realistically very little difference between 9th and 11th place finishes - but there is a huge difference between 74 and 91 points (all else equal). So you are claiming that OTHER players impact is what results in the point difference, and not actually Wheeler being better.
So by this exact same logic, how can we compare Mackinnon's 140 points last year to Crosby's 104 point Art Ross? Because Crosby didn't have the Rantanen and Makar and young talent that all magically increased league-wide goal scoring without improving goaltending or defensemen ability to defend.
