You can point to outliers at any stage of development. Fact is, Dvorsky was in a terrible situation for a young prospect. The fact that he struggled for his first 10 games doesn't mean he couldn't have figured it out on a team that could've given him a longer leash. His team couldn't afford that, because they were pathetically bad. What were they, something like 5-16 to start the season?
It was an awful situation for a prospect and he wasn't given a fair shake which is why he ended up in Sudbury where he absolutely dominated. If you can't acknowledge why that would be an awful situation for a player that was one of the youngest players in his draft class, and you think instead that he "stagnated", then we'll just have to agree to disagree.
You keep acting like Dvorsky's play had no impact on the fact that he couldn't keep a regular spot in the SHL when the reality is that multiple posters who watched him said that he was actively the worst player on his roster, and acting like Dvorsky being a June birthday instead of like, a March birthday had literally any impact on this is insane. It's clear to me that you have no interest in an objective assessment of Dvorsky as a player or as a prospect and just want to make excuses for him.
By the way, I watched a metric ton of Dvorsky in the OHL this season because of Quentin Musty. If you're impressed that he can physically bully kids, great. I'm not.
Let's go back, ten years of Swedish forward prospects drafted in the 1st round, and look at the even moderately successful ones.
William Nylander (9th overall) D+1: PPG in ~20 SHL games, then jump to the AHL
Adrian Kempe (29th overall) D+1: 17 points in 50 SHL games
Joel Eriksson-Ek (20th overall) D+1: 15 points in 41 SHL games
Elias Pettersson (5th overall) D+1: 56 points in 44 SHL games
Isac Lundestrom (23rd overall) D+1: 9 points in 17 SHL games, then 6 in 12 AHL games
Alexander Holtz (7th overall) D+1: 18 points in 40 SHL games
Lucas Raymond (4th overall) D+1: 18 points in 34 SHL games
William Eklund (7th overall) D+1: 14 points in 29 SHL games, considered "disastrous"
Hell, Nils Hoglander, drafted 40th overall in 2019, scored 14 points in 50 SHL games in his D+1 season. Fabian Zetterlund, drafted 63rd overall in 2017 with an August birthday, scored 7 points in 35 SHL games in his D+1 season.
If anyone is the outlier, it's Dvorsky. It's extremely, extremely common and basically a rule that a highly-drafted forward prospect developing in Sweden who is going to amount to anything is capable of locking down a full time role in the SHL.
Filip Bystedt is on track, Otto Stenberg is on track, David Edstrom is on track. The few in the last couple years who haven't are the guys like Lekkerimaki, Ostlund, etc. who have been in the Allsvenskan because their teams were relegated and are very physically underdeveloped; Dvorsky has man strength already.
Edit: And Lekkerimaki, Ostlund, and Ohgren were actually relegated and had SHL games played in their draft seasons, so you can't use Dvorsky's horrible relegation team as an excuse.
