Ok let me explain what should be obvious.
Edler get's shots any dman would with the Sedins the coaches want him shooting a ton they think either he scores, rebounds are to be had and opens things up for the Sedins. The sad thing is any dman with a shot as hard as Edlers should have 15 goals easy getting all the chances they get with the Sedins. He gets a lot of shots but he misses the net far too often and could be far more productive at it from what is see.
To clarify i deleted part of your post, not because it doesn't support my argument, but because my paragraphs are long, and i don't want this entire post to take up half a page.
One part made me laugh really hard when i glanced by it the first time. Edler's weak on retrieving dump in's? That should be fairly obvious. That's like saying... Well Schneider is a great goalie, but he lacks that finish in the offensive zone. News flash buddy Edler isn't supposed to get the dump in's. He's supposed to ring it as hard as he can from centre and have a good forecheck supporting him. If Edler is aided by the Sedin's, then Garrison's 16 goals were aided by Campbell who is a slick passer. Our defence core is looking pretty weak then. The players around you are supposed to make you better, hence why they are your teammates. Edler's hard shot aids the twins when they play, just like the smooth passing of Campbell helped Garrison. What your essentially saying is that unless a player can do it all on their own... such as Sidney then they are utterly useless, since the point of hockey isn't to work the pucks off your teammates to get the best results for your team. I have never played in high level hockey such as junior B, or WHL, or any of those high level leagues, but i can tell you right now that passing between teammates is a far better solution then doing it all yourself. Again I am a fan with my own opinion, but I believe that Edler helps the Sedin's, not as much as the Sedin's help him, but he is a strong force playing with the twins.
Now going onto the "good defensemen" logic. Erik Karlsson doesn't strike fear into anyone. Hell he doesn't even strike fear into me, but his skating ability and offensive flair make him such a good defensemen. Phaneuf is very inconsistent, yet he still strikes fear into opposing forwards just like Edler puts fear into the likes of opposing forwards. Different players can do different things, and the Canucks aren't so fortunate that we can ignore skill, just because we want to have more grit. Brian Burke tried that signing Mike Komisarek and making his team bigger, meaner, and tougher.... We can all agree as Canucks fans that the leafs are unsuccessful at the moment.
To conclude, I am not in denial. I understand that Edler has been inconsistent in the past, but he's working to develop his game. Every player gets on hot and cold streaks, even the Sedin's and Kesler arguably our best players. If we let Edler walk, we might have KC to plug the gap, but I wouldn't be too confident about our defence group with him as our bottom pairing. Even Nashville who had a guy like Ryan Ellis in the wing, and who seem to do nothing but churn out defensemen after defensemen have nightmares over letting Suter walk. The Canucks are not that good at developing quality defensemen consistently. Yes we have hit gems in the past such as Bieksa, Tanev, KC(hopefully), and Edler. I am not Edler's biggest fan boy, and I can see that he has flaws in his game, but he's still only 26 and he has plenty of time to improve.
P.S. I am trying to convince you to see my side of view, just like you are trying to give me your side of view. That is how a message board is supposed to work correct?
