Quoting: TheDream_43
Dermott is a younger option, and Johnsson brings a young skill to you guys to replace Zucker (if moved). My thought, don't watch a ton of Min though so could be wrong!
The thing is the whole reason we'd trade Dumba, Brodin, and Zucker in the first place is because we already have too many D and too many wingers. We currently have five top 4 D with Suter, Spurgeon, Brodin, Dumba, and Soucy so that's why there are all of these Brodin/Dumba rumors. Those two in particular probably have the most trade value of any of our players, which adds fuel to the rumor mill. Trading one of them for younger D doesn't make much sense since we would still have four top 4 D and we have a few promising D prospects budding in Iowa (RD in particular, but Soucy would replace whoever we trade as he can play both sides very well on the 2nd pairing). We also currently have Zucker, Zuccarello, Parise, and Fiala as our top 6 wingers but we will need a spot for Kaprizov next year, so one of them will likely be moved. Parise and Zuccarello likely have negative value in a trade and Fiala is our most skilled forward, so that basically leaves Zucker as the odd man out. Replacing him with a Kapanen or Johnsson doesn't solve any issues, we'd still need a spot for the best winger outside of the NHL next year if we targeted Kapanen/Johnsson in a Toronto trade.
The Wild's #1 bolded and underlined need is talented center prospects/young centers. Any trade we make should target a young center (not saying we'd get any of these guys but examples would include Suzuki, Krebs, Heponiemi, Texier, etc.). Toronto doesn't have any prospects like that and the one player they have that fits that bill (Matthews) would get Dubas fired if he traded (and rightfully so unless it's for like McDavid). long story short, I don't see a fit between Toronto and the Wild as trade partners. The Wild have a lot of enticing pieces for Toronto, but Toronto has nothing that would fill our needs.
Edit: and for the record, I do like Dermott and I do like Kapanen. Haven't seen enough of Johnsson, but the only thing we need less than any winger and defenseman is a left shot winger.
