Would Dumba for RNH be fair?
I would do it in a heartbeat, but I don't think Edmonton would.
RNH needs a new contract, and will likely be asking north of 7.5M...certainly more than 7M. Don't see MN jumping all over that.
Anyway, to answer the OP; it's impossible to answer the question because Dumba has to reestablish himself as a legit offensive force before he will be even desirable at his present cap hit of 6M. He has looked good this year, is scoring, and the shot seems to be back, but teams will want to see him for a stretch of at least 25 games before he becomes a sought after asset again. And of course, if he does do all that, will MN even want to trade him?
