If I had to guess, Purcell is the only one moved by the deadline. Fayne's contract will scare teams off and Schultz isn't very appealing to playoff clubs due to his shaky own-zone play/softness. I do think half the players mentioned will be gone by the start of next season though. From the ones listed:
Eberle: I'd be surprised if he's moved. Tons of rumors all year, but he might be the only sniper we have and he has chemistry with all our top guys. Good plug and play for our top 6.
Fayne: Might be able to find a taker in the Summer, but we'd likely be taking a bad contract back. He's not a terrible depth guy (although overpaid), so it's really 50/50 what happens with him.
Gryba: I wouldn't be surprised if he's re-signed as depth.
Lander: Not worth anything but a contract spot. Probably sticks around as an AHL call-up type. Unless he asks to be moved for a better chance elsewhere.
Purcell: Gone. His offense will lure someone and he's a pending UFA. So not much risk for the acquiring team.
Schultz: I could see a non-playoff team taking a shot in the Summer. Might be after we walk away from the qualifier though. He won't be back.
Yakupov: I like the kid and think he has (most) of the tools to become a player in this league, but right now he's hurting the team more than helping. If we can find palatable deal, it's probably best for everyone to move on. We need to start taking steps and can't wait for him to figure things out. Again, a Summer issue to deal with.
