Granlund is a bandaid solution. Horvat is a legit top 6 C with an excellent defensive game which is needed to play with Laine and a rookie Demidov, that's something that Granlund cannot provide.
It most definitely is not "way" better. That 1st is far from guaranteed to be "extra late" compared to the worst one we have in 2025 and 2025 is seen as a poor draft class in terms of depth. Definitely better odds that the Avs regress as they will lose depth, and need to pay others way more. Hage is better than Ritchie but Ritchie is still a damn good prospect himself.
For the sake of the argument, let's say our 1st is around 5 spots higher than the Avs one but in a worse draft class, and Hage is one tier ahead of Ritchie. We're still getting a younger player with more term at a cheaper AAV (I mentioned how Isles would have to retain in this trade). I think the package is relatively comparable but let's stick to your evaluation of it. If what we're offering is "way better", then what we're getting in return is "way way better". It's still not comparable. You're not getting Horvat for 1st+Beck/Kapanen+2nd which is a "way way way worse" offer.
