As noted, scoring is lower this season than the previous two.
But, in general, the reason there are more high-end point seasons lately is the reduction in goalie equipment c.2017. There was a small spike right after that. (What's hilarious is that it took the NHL and its owners about 20 years to deal with the low-scoring problem.)
Not only was there a spike then, but I also noticed (almost overnight) more distance shots going in, more short-side shots, more shots upstairs, more tricky shots by the goalies' ears, etc. All this has become common strategy by 2024. So, the offensive players have adapted to the advantages that the high-tech whippy sticks gave them.
And yes, over-expansion of the NHL means there are more AHL-level players now with big-league jobs. But that doesn't necessarily increase scoring (see: late-90s). It's more that the teams' strategies have shifted and high-end players have developed new and better strategies, aided by the equipment.
I actually questioned this, on the History forum, about a year ago and we had a brief thread about it.
I agree. There is really no legit reason why only 1 goalie should play an entire game.
