It's not a matter of value, his inconsistency, and gaffes far outweigh any positives. I don't wish him ill will. He's in a position where he's relied on as a top d-man, and clearly can't handle the pressure or the minutes.
We should trade Edler to Team Sweden. He plays good there. I think Karlsson would be a fair return. He has zero games played with Sweden this year. Sweden doesn't need him.
Alex Edler was fine until the last 20 games of the season when he appeared to simply give up/got tired, whatever.
The Canucks have to rebuild somehow, and I think you get more for Tanev than Edler. You also can't trade them both or things turn into Edmonto circa 2009-2015.
