St. Louis fans are way overvaluing Parayko, but I can't blame them. He's a good defensive d-man but d-men who don't break the 40 point mark don't bring back the kind of returns they are looking for, regardless of how good they are in their own zone. St. Louis would be better off keeping him as I think the best they would get would be a mid-first and a prospect and I think he's worth more than that to the team.
I think Buchnevich, now that he is a one year rental, will bring back a 1st and a prospect. I would trade Detroit 2024 1st, 2025 2nd, and Berggen (or Wallinder) for him but I suspect Yzerman is going to use his first on another player that Detroit fans will see in the NHL in like 2031.
