Yes, but on this and another thread, the trade deadline isn't about remaking your team by, say, trading Lindell for an equally talented forward. It's about sacrificing future assets to add to your weakest areas, which again, for us, would be scoring forward.
And, just a few weeks ago, I read an article about how total rebuilds aren't really necessary or effective, contrary to what the average fan wants.
And, just look at our history. Gainey built a cup winner in a few seasons, with Verbeek, Belfour, Hull, as UFA. For additions by trade, it was Guy, Zubov (steal!), Sydor, Skruds, and Keane. 8 out of 20 or about a third of the players, probably two each over three seasons.
If you think this version is in better shape, with Seguin and Bishop coming back, then it should only take 3-6 additions, maybe over 1-2 years instead of 3-4 because of the team age. The first three were UFA, which is less likely to happen now. Nill has had two "big steal" trades, and hopefully he is due for another one in this off season.
