If we go by same rules for this draft we protect.
1.All players who have currently effective and continuing "No Movement" clauses at the time of the Expansion Draft (and who to decline to waive such clauses) must be protected (and will be counted toward their club's applicable protection limits). So that leaves Buff as someone we have to protect as he will have a modified NMC, which is still seen as an NMC.
2. All first- and second-year professionals, as well as all unsigned draft choices, will be exempt from selection (and will not be counted toward their club's applicable protection limits). So that means guys like Niku, Harkins, Appleton etc. will be available as they will all be 3rd year pro's at that the time of the draft.
7F, 3D, 1G
Scheif, Laine, Ehlers, Connor, Roslovic, Armia, Wheeler (likely NMC)
Buff (NMC), Trouba, MoJo
Hellebuyck
That leaves Copp, Little, Perreault, Dano, Tanev, Lemieux, Petan, Appleton, Spacek, Harkins, Hendricks, Kulikov, Myers, Chiarot, Morrow, Niku, Poolman, Mason, Hutch and Comrie off the current roster that will not be protected. It's likely a few of them are gone but Seattle is likely going to go after a solid young guy like Appleton I'd imagine. It's possible he jumps someone and gets protected. There will also be Niku and Poolman available should they decide to go with a D. Either way Seattle is going to get a very solid player from us. Or we will have to make another deal.
