I think you could get Puljujarvi for less. Why not try him for Thompson straight up? Both players careers have stagnated, maybe a trade will help them both out.

Puljujarvi is a Great addition for the sabres and I believe would fit in well!

Sabres don’t need another defenseman

Think you guys would slide far enough to get him? You're picking 9th or 10th right now, and there's a couple of teams that you could slide past, but most mocks I've read have him going top 5, if not top 3 after Laf/Byfield.

Edit: Stick with upgrading the forward core, lots of good dmen on the Sabres...if you slide up to 6-8, you could probably get one of Perfetti, Rossi, Lundell (My fav of the 3-10 projected guys), Holtz or Holloway. Or, go the alternate route and pick a sure-thing future tendy in Askarov.
