Haven't read this entire thread, but no, I don't believe the Wild need a total blowup. Few teams do. Blow up is a typical fan over reaction and not practical or necessary. Winnipeg didn't do a complete blow up to get good, they drafted over years and years and it is coming to fruition, with a few trades by the GM.
Good teams don't need to get rid of many players, they just need to keep what they have and supplement them. The Wild just need a few good players.
In big trades, the team that gets the best player wins, so trading their best for a collection of lesser players (assuming both GM's understand the value when making the trade), makes no sense, unless the Wild just can't fill a roster otherwise.
Trading quantity for quality would make some sense, but then what other GM would do that? It does happen, and if the Wild have some players in the pipeline, it could make some sense from their perspective.
The good old fashioned hockey trade, from areas of depth (D) for more scoring might help, but is hardly a blow up.
Trading a known commodity for a good first round pick has its ups and downs, with no immediate result, plus no guaranteed the player at position X is any better than the one they could pick at Y. And, they would have to replace the player they traded somehow, unless, see above, since one for one trades don't add to the number of good assets a team has. In any case where you give up an asset, you need to get at least an equal number back.
Basically, they can draft a Phenom or score in UFA, or hopefully both, getting great new players without giving up other assets. And hope your GM makes all the right moves, which is what it takes to build a special team.
Just like the 30 other teams (save Vegas which had the expansion draft)
