Well, look at it yourself. Byram + Helenius (our best prospect), and in the other deal you just trade Willander for Andersson. To me, that's weird. The value is different. Byram and some minor upside for Andersson is fair, but nothing more. I wouldn't trade Power for Andersson either.
Andersson would probably be an improvement for us, but not that much. ( I mean anyone can play with Dahlin and that player will almost always look decent). We still need to get another top 4 RD, a top 6 C and a good winger in the top 9. Our assets are not endless either.
