I'd move Misa for Dahlin, Hughes, or Makar, and a top top 4 pick for Seider, Faber, Sanderson, Lacombe, Edvinsson, L. Hughes, Buium, Levshunov, or Parekh.
I'd consider Vlasic and Guhle because they're 100% the type of d-man you win with, and they have great contracts, but probably pass with the hope I could draft and develop my own lockdown guy by the time the team is ready to compete.
While I'd love to add Byram, Dobson, K'Andre Miller, Nemec, or Clarke, I wouldn't offer up that premium of an asset. If one of these guys is available, who do you see offering up an elite center prospect (better than your choice of Hagens, Frondell, Desnoyers)?
St. Louis (Dvorsky), Seattle (one of their big three), and Columbus (Lindstrom) seem the most likely (defensive need, desire to fast track, better than Musty+1st+), but none of them seem particularly likely as they need centers just as much as dman.
Elite teams will move premium prospects including centers, but Ritchie is kind of the last one who was owned by a contender. Detroit (Kaspar/Danielson) and Buff (Helenius/Kulich) could, but they're neither ready, and they need centers more than D.
