I haven't read the entire thread, but even if I did, I'm not sure how or why the conversation turned from "Huges for 2nd overall" to "Hughes vs Dahlin". All I would say on the latter part is the following:
- Hughes has had a more seamless progression, betting better each year. Fantastic player, and it's rare that young Dmen have the kind of linear progression he has had, rather than the usual ups & downs. Big testament to the quality, smarts and commitment of this player.
- Dahlin is going through the typical ups & downs and inconsistency that the vast majority of young Dmen go through.
- We will not know who the better Dman between these 2 is for about 3 more years.
- The both play very, very different styles of games. Just because they both have offensive skill and the ability to produce offence, theat doesn't make them any less apples vs. oranges.
As for the origianl proposal: from a pure value point of view, the 2nd overall pick for Hughes is not unreasonable. I would want at least a little something extra if I'm VAN just because Hughes is established (NJD's 2nd rounder this year, because it's high in the 2nd round may be enough of an add). HOWEVER, from a context point of view, VAN is not going to trade Hughes for a 2nd overall pick in THIS draft. That is what the OP wasn't aware of and should have been, since Hughes is a key part of the core and this draft doesn't have a generational player worth deviating from that core.
On the other hand, if the offer was Hughes for the 2nd overall pick in 2023, as much as VAN doesn't want to trade Hughes, they wouldn't be able to pass on the generation type talent that should be there at the top of the 2023 draft. But no such offer would be made by whoever has the #2 pick next year so it's irrelevant. However it is instructive that not all 2nd overall picks are equal and the players at #2 this year are approximately equal in value to Hughes, not superior, so VAN would have no reason to make that trade -- unless they decided to blow up the entire team and start fresh, which none of us see happening.
