Honestly I agree with a lot of what you said here (especially the first part- I will definitely be way off on several players in this draft).
I think our disagreement here is mainly one of degree. I have Eklund as a top 10 prospect this draft, I enjoy watching him a lot. You yourself even agree that you're not expecting him to hit the career highs that Zetterberg, which is essentially the point of my comment above. I'm not really criticizing Eklund so much as showing pause to that comparison. I could say the same about most top prospects. Let's take the top 3 picks of the last three drafts for example (Dahlin, Svechnikov, Kotkaniemi, Hughes, Kakko, Dach, Lafreniere, Byfield, Stutzle). It's very early, but I don't think there's a player in there I'd confidently project to be as impactful as prime Zetterberg right now.
I think Eklund is a pretty low-risk prospect (or high floor, if you like that terminology). If I thought there was a pretty significant chance of a Zetterberg upside, he'd be my no-brainer #1 pick. I think his upside is a bit more muted than that, which is why I have him in the #4-10 range. I don't think our evaluations of this player are all that far apart.
Edit: I missed the last part about Raymond. I don't see that as blasphemy at all, I think they're in a similar bucket as prospects. I prefer Raymond's upside to Eklund's but I get why people would prefer Eklund as well.
