I think the only viable trading partner for the Wings at this point is the Carolina Hurricanes. They have a slew of young defensive prospects both currently on their team (Faulk, Murphy) as well as in the pipeline (Hannifan, Fluery, Carrick, Slavin, Pesce), but are painfully weak in star power and prospect depth up front, specifically at wing.
Obviously, the blue chips of Hannifan and Fluery will be the cornerstones of their defense for years to come if they reach their potential and would most likely come at the steepest price.
The player that I constantly want on the Wings, is Justin Faulk, who I believe is a very solid Top Pairing Right Handed D and is under a very competitive cap hit of $4.8M for the next several years. This is a kid who is criminally underrated as being the backbone of Carolina's defense, who has seen his point production increase year over year (topping at 49 points this last season) and is entering his prime for the next 6 seasons or so (currently 27 years old).
The Wings have a glut of young wingers and prospects that could certainly improve Carolina's Top 6, and since they are in full rebuild and looking for youth, draft picks would probably look particularly desirable for them.
I suspect if they could flip Faulk for a Top 6, young Forward or Blue Chip forward prospect, another quality prospect, and a draft pick - I'm guessing that they would bite on something like that.
Assuming Pulks proves himself to be a legitimate scoring winger at the NHL, that would give us Tatar, Nyquist, and Pulks as quality young 25+ goal scoring wingers. One of those, alongside a Bertuzzi or Holmstrom prospect, and a draft pick could land us Faulk who would immediately be a Top Pairing, RHD to go with Dekeyser as what would be the future of our D corp and use the
next three years to try to continue to develop and acquire more defensive prospects.
