I find it amusing that this trade essentially undoes the previous trade for both clubs.
I think I disagree with this.
Both clubs got a prospect D man (Erixon is doing better now, 5 years from now we'll see) so call that a wash.
That leaves AA and Dubi for Brass and DD. Now I love me some DD as much as anyone else but both AA and Dubi bring more to the table for actual skill. Plus with Dubi, JMFJ, and co stepping up as leaders DD became a bid redundant there too. SO we improved over DD (honestly fan love aside). Brass has the skill to be a legit top 6 but he only finds it so often. Consistency is a huge issue. Meanwhile AA has been bringing that every night. He's also better on the draw and defensively.
Summary:
In the swap we improved our hardworking nature and defensively with the players we picked up. Plus we got a 1st round draft pick so we haven't undone that Nash trade at all.
Note this is all the CBJ perspective.
