Quoting: OldRedFox
Liljegren is at least two years away and has a lot to learn about playing D, the fact that he would be Vancouver's best D prospect is more an indictment on their drafting. Liljegren is a good prospect, but not a blue chipper. Edler slots in at second pairing left side easily and unlike the other Leafs D can actually play defense. Edler played very well on a very bad team last year. Gudbranson is a guy the Leafs have had a lot of interest in and beats out Zaitsev all day long. Guddy is younger and skates better than Polak (doesn't everyone).
You are a typical Canucks homer, Guddy is the worst defenceman on a terrible team. He isn't worth the league minimum, neither is Polak. Zeitsev is Right Handed, younger and when healthy, better than Edler. Edler is older and declining and Rielly, Gardiner and Dermott are better than Edler, better skaters, better offensively and in the case of Rielly better defensively and better physically as well. Also I'd like to stress, Edler is declining, rather rapidly at that.
Liljigren, until he got Mono in his draft year, he was considered as the potential 2nd overall pick last year. He was an absolute steal, and yes he is a year or two away but still would instantly become the Canucks best defensive prospect. To give a team a top level prospect and a 1st round pick, you better be giving extreme value the other way. Your trade idea is basically the Canucks give up a tractor (Guddy) and an old beat up Toyota Corrola (Edler) for a Tesla (Unproven but high potential prospect) and a Concept Car (1st round pick that could become a huge winner). Tell me, in what universe does anyone ever do that?
The only trade TO makes with Vancouver is for Tanev.
And before you say Toronto offers up Marner, Matthews and 18 first round pics, the trade would be something like Tanev to TO for this years 25th pick or Tanev to TO for a 2nd and a prospect like Rosen or Borgman or something like that. Maybe two B level prospects and a 2nd. The Canucks just don't have much to offer and what they do have isn't as good as other options. (There are safer, better or less expensive options available for right handed defencemen.)
