My 3 cents:
Clayton Keller - Keep for the Core.
Nick Schmaltz - Good guy. Has 1 year left on his contract, I think. Keep him until close to Trade Deadline, then, see if somebody wants to overpay. If not, re-sign him.
Lawson Crouse - My favorite 'Yote. Keep him!
Alex Kerfoot - Another decent player. Deadline deal unless he does more than expected.
Matias Maccelli - Part of the Core.
Nick Bjugstad - Fantastic leader for the young guys. Keep him.
Barrett Hayton - Wasn't much on drafting him to begin with. Maybe he kicks it up a notch, but, trade him if he doesn't.
Logan Cooley - Core, baby!
Liam O'Brien - I like these type of guys. Glove dropper, shit disturber. Protects his mates. Find out what he sees his role as, then, decide accordingly.
Michael Carcone - Good soldier. Seems to know his role well. Keep him.
Sean Durzi - Needs to beef up his defense a bit, but, a good player. Keep.
Josh Brown - Another guy I root for. Every team needs tough guys. Keep him if he wants to stay.
Juuso Valimaki - Decent D-man. Could get better with this team. Keep.
JJ Moser - Great player. Can get even better. Keep him.
Travis Dermott - Has good shifts and bad shifts. See if another team wants him for a pick or two.
Karel Vejmelka - Good goalie, but, kinda lost his way this year. Could bounce back with another team.
Connor Ingram - One of the best waiver pickups this year. Plus, he's looking forward to playing in SLC. Keep the man!
