I'm an enormous fan of Hunter Brzustewicz, I had him in the 1st at the draft. I think he has top pairing upside, and the complaints about his skating and defensive play are overstated. His IQ is elite and he takes over games. That said, there is a non negligible chance that he goes to the AHL next season (he was a late birthday draftee) and falters at the pro level. If he does, his value is nowhere near what the Canucks got out of him today.
I am also a huge fan of Elias Lindholm, I think he is a piece that if he clicks puts the Canucks over the top. Brzustewicz is probably 4-5 years out from being an impact NHLer.
The rest is negligible to me, Kuzmenko was awesome last year but he and Tocchet had bad beef and he had no value after all the scratches and poor performance this year.
