Faksa is exactly what we need, change the 2nd to a 3rd or a B prospect and I'd do this trade in a heartbeat. As Dallas fans have already noted however they have no need to move Faksa...perhaps there's a slim chance he's available if he wants 3.5m+? Van can't really afford him in that scenario either unfortunately.
But excellent target by the OP, would dramatically improve the bottom 6 and free up Horvat from matchup duties - I suspect Horvat would have his best offensive year ever in such a scenario and the Canucks would be both better defensively and offensively.
