Context matters whether you choose to believe it or not. He had a career high in goals with 24 and missed 18 games, had those 48 points and missed 18 games so not just a "50 point" center if we're taking this season into account. You say Dumba is a 50 point Dman but he only had 50 points in one season, had a career high of 34 points this season.
It's great that he had a breakout season and I understand why Wild fans don't want to deal him but his valuation in this thread is out of control. If the Oilers are offering RNH+9th overall, the Wild better add something significant to Dumba, RNH+9th for Dumba alone is insane overpayment and would never be offered in the real world although with Chia you never know.
Either way, there's no deal to be had here that will appease both fanbases so a friendly agree to disagree and we'll all move on.
