The Wild actually have tons of Cap Space, with very few players to sign (and those needing signed not projected to take up much cap space).
They take advantage of that space here to significantly upgrade in G and upgrade C depth (their two biggest weaknesses), and get a 1st rd pick, while shipping out a Dman they need to trade within a year or lose for nothing to Seattle.
They have $12M, and after your trade, they have $10M to sign Greenway (2.0-2.5M), Kunin (3.0-3.5), Sturm (1.0-1.5), Soucy (1.25-1.75), and if returning Koivu, and Galchenyuk
They do need to ship Dumba, I agree, but they can get more than these spare parts offered, this offer is a better goalie on a 1 year contract, a 3rd line center, and a 4th liner and a 1st pick, which likely is late first round with the addition of all these pieces.
If you take Dubnyk with no retention, then, maybe this gets closer.
