SHLs highest isnt chopped liver, which is exactly why I'm saying it's getting easier to score now. If you have multiple guys in a 2 year span able to outscore lidstrom, ohlund, and hedman, it kinda says it's easier to score now than it was when the greats were playing.
In 89-90 when Lidstrom was in SHL, there were 22 swedish players getting at least 1 game in NHL.
Last year, that number was 100 players.
Yes, the SHL is "easier" these days. The talent is more diluted, with young guys leaving for NHL/AHL earlier, with older guys going to KHL or other euro leagues to a higher extent than they did 30 years ago.
That doesn't mean the SHL is a bad league, the depth of talent is still good. But what happens is that it becomes easier for 18-19 year olds to get significant opportunities.
Also when looking at historical U20D scoring, keep in mind Hedman and Dahlin (and some others) did it as 18 year olds. What would they have done as 19 year olds? Probably comparable or better than Lundkvist/Seider.
ALL those things said, given the type of player that Seider is; the offensive numbers are definitely something to be excited about. As we can see, there are other highly touted D prospects that can't put up numbers anywhere near that level (Broberg, Björnfot etc). So it's not like just anyone can do it, but I don't think the comparison to 30 years ago is very meaningful.
