To see so many fans leave Rasmus down low or off their list is telling and evidence of how much loving shiny new toys isn’t just for pro players. And it’s another strike against the Kings development group.
Yet Vilardi was often rated higher than Kupari when Vilardi was still considered a prospect. Even with his injuries and uncertainty of recovering.
By your logic, if people picked solely because of "newness", Kupari would have been rated higher.
Kupari being rated lower has been explained by me and others. However, if you need additional assistance, the further removed a player is from their draft class AND the further they are from playing their projected role, the lower their value.
Kupari may get time on the top line this season. However, these are the players ahead of him on the depth chart in each forward position:
LW
Iafallo
Kempe
Andersson
So if used on the left, Kupari would be in the Frk/Lemieux/Wagner/Grundstrom range
C
Kopitar
Vilardi
Byfield
JAD
So Kupari would be in the Lizotte/Turcotte range at Center
RW:
Arvidsson
Moore
So Kupari would be in the Brown/Frk/Kaliyev/Tkachev range
For a highly-skilled winger, he's struggling to land a top-6 role. Injuries have played a part, sure, but Kaliyev has passed him on the depth chart by virtue of rounding out his game while displaying better playmaking and scoring ability at a younger age.
That's when he might project to play in the middle-six. He has more raw skill than Thomas, but Thomas' utility will likely move him around the lineup easier (oh, and Thomas was drafted in the same year as Kupari, so it's not a "new toy").
Kupari's raw talent may not land him a top-6 role on the Kings. And he's not an energy forward. That affects his value.
