I would love to see players stats if only the first assist was counted as an assist.
Not much changes in 2022, at least at the top of the race.
McDavid is 1st either way. Stamkos and Tkachuk remain in 7th and 8th.
Gaudreau, Draisaitl, Matthews and Kaprizov each move up one spot. Huberdeau drops three spots. The top eight are identical, and only one of them moves more than one spot.
Looking at the top 50, the three biggest drops (the only ones whose rank drops 15+ spots) are all defensemen - Jose, Makar and Hedman. This should surprise nobody, as secondary assists disproportionately go to defensemen.
Of the top 25 players in points, 18 of them are in the top 25 if you drop the secondary assists (three of the exceptions are the defensemen I just named). Four other players drop out of the top 25 - one falls to 26th place and two are tied for 27th place. The only forward who looks much worse without secondary assists is, surprisingly, Nazem Kadri, who falls from T-19th to 30th.
In general, I think people make a much bigger deal about secondary assists than they should. It does impact the scoring race, but I think a lot of people expect it to have a much larger impact than it really does (especially since, like I said, it's defensemen who get a much greater share of secondary assists).
