Trouba has to be traded. I see no point in keeping him as an own rental now.
Wheeler and Buff should be traded. I think Wheeler and Schief are the root cause of the discord on the team but Scheif could still be salvageable with Wheeler gone. Wheeler trade has to happen fast before his NMC kicks in.
Buff may be loved but he's a declining asset and I think Bad Buff shows up too often. That was in evidence last night in a critical game. He can still be traded to the 17 teams not on his no-trade list. Take the best offer (preferably in the east) and move on.
With Wheeler and Buff gone, Little might feel like the old gang has broken up and waive his NMC for a desirable location. Maybe Vegas will want him. Every player loves Vegas. Every player wants to be a Golden Knight. Who wouldn't waive his NMC to play for the perfect team in the perfect city? Even if he gets press boxed, I'll bet they have the perfect buffet up there cause they're just so much better than everyone else.
