Most fans (especially on HF) massively overvalue draft picks. Which is why most fans also hated the previous similar trades Brisebois made (Coleman, Goodrow, Hagel, Jeannot).
And while the Jeannot trade was bad, there's a lot of hyperbole around this trade that will die down once people get a read on what Nashville got. Frankly we already have a pretty good idea:
Cal Foote is playing in Slovakia (also, charged with sexual assault)
This year's Tampa 1st rounder (and as established in this thread, late firsts rarely yield useful players)
2024 2nd rounder - Packaged with Jesse Kiiskinen to get Andrew Gibson. Looks like a rough trade now, with Kiiskinen looking like a slightly better prospect.
2023 3rd rounder - Dylan Mackinnon - 2nd-pairing dman on his QMJHL team in his D+2 season, with 6 pts in 50 games. Doesn't augur well
2023 4th rounder - Pick reacquired by Tampa in a 4th round swap. Nashville used their pick to draft Juha Jatkola, a goalie who's numbers in Liiga have decreased since being drafted
2023 5th rounder - Pick was used to move up 4 spots in the 2nd round, to draft Felix Nilsson. Nilsson is having an ok SHL season, though is probably still a long-shot to be an NHLer.
Still a bad trade for Tampa, since Jeannot was a bad fit, but all those picks aren't nearly as valuable as people think. And I think it's the same for yesterday's move. Seattle probably gets one useful NHL player out of these three picks, plus a solid young 4th liner in Eyssimont. A good trade-off for a team that won't be contending soon, but it's likely not something that will change the trajectory of the franchise all that much.
