Well, here's a post I never expected to make but am happy too...
Here are his 22 yr old comparables
Zuccarello (MIN): 1.14
Bergenheim (NYI): .92
Olofsson (Buf): .86
Holmberg (SHL): .84
David Vyborny: .82
Daniel Alfredsson: .82
Linus Karlsson (SHL-CHI 3rd rounder): .80
Mattias Janmark-Nylen: .66
Young players scoring in the SHL is actually kind of rare (Willy was a generational level prospect in their system). Holmberg is one of only two 22 & under players in the SHL in the top 30 for point scoring (Holmberg is 11th, and Linus Karlsson is 19th). There haven't been many 22 and under players to score at .80 (1980 birthday or more recent) or better and not go on to be some sort of a functional NHL or better.
Here's the list (not including names above):
21
Huselius (5x 20+ goal scorer, 1x 30 goal scorer in the NHL)
Silfverberg (4x 20+ goal scorer)
Soderberg (1x 20+ goal scorer and analytics darling)
Rickard Wallin (lol, yeah, same one)
Andreas Johnsson (yeah, same one. 1x 20+ goal scorer)
Tom Wandell (229 NHL games0
20
Henrik Zetterberg (lol)
Jonatan Berggren (Detroit 2nd rounder, never came over)
David Rundblad (hyped prospect who didn't pan out)
Oskar Lindblom (good player, career derailed by cancer. 17 goal scorer as a rookie)
Oskar Steen (skill midget who didn't come over until much later in his career and didn't really crack in any real way)
Viktor Arvidsson (2x NHL 30+ goal scorer)
19 (go back to 1970 for this one...because)
Elias Pettersson
Peter Forsberg
Markus Naslund
H Sedin
D Sedin
Nick Backstrom
Marcus Kruger (one of these things....)
18 (1970 again)
Markus Naslund
William Nylander
D Sedin
So obvious the quality decreases with age as the the best players are generally coming over at 19-20-21, but there aren't a whole lot of true misses in that category either and most of the names turned out to be pretty solid NHL'ers. Middle 6 types or better.
