Wild could use help on the wing, sure. But given they're in the playoff mix I'm not sure they'll be looking to move Dumba and weaken their D, I could see them just using him as their own rental given his deal is up at the end of the season.
If Minnesota really wants a forward it'd make more sense for them to go after a center anyway imo, I don't see Steel as a long-term solution as their 1C. They could really use another top 6 center to compliment Eriksson Ek. They'll have nearly 15M in dead cap the next two seasons, at least acquiring a center could help keep Kaprizov happy.
