I'd also add that, personally, I'd have a hard time considering any wingers that didn't meet the following criteria:
- is 24 or under
- has more points than Dumba this year (24)
Those aren't set in stone, but if we were to trade Dumba it'd have to be for youth and scoring power. At 23, he's on pace for 17 goals and 45 points and his past performance indicates that that's in line with his development curve. It's not a fluke and it's probably not his peak. His defense is also improving and is comfortably middle-pairing quality. There's absolutely top-pairing upside there. Zero character or health issues. There is no reason to trade that away without a compelling player coming back.
Centers I'd be a little more open-minded about, but not much.
