Quoting: LobbysOilers
there's an 8th overall pick going back to them. since they can easily afford them theyd be incredibly stupid
8th overall is about what it would take to dump Lucic, free and clear. You might get Chlapik in return if they've completely given up on him.
Russell and a 3rd for a 2nd might work for a team desperate for a 3rd pair LHD, but one looking for depth to contend and you'll probably have to retain or more likely take a player in the $2M+ range back, in order to balance the contracts.
Value wise, I wouldn't say it is outlandish, but it's far from "an offer too good to refuse", as you suggest.
Nurse is the one D the Oilers can't consider moving. Nuge for Ehlers might benefit both teams if Winnipeg decides to shuffle some pieces though.
You'd be lucky if you could give Gagner away. For a player to go through 7 teams and trips to the minors in a span of 6 years, there's an issue somewhere.
