Saying Ritchie is a similar mistake to Virtanen is just wrong. Ritchie was the consensus pick with that number 10 pick at the time, it sucks he hasn't become the power forward we were hoping but there was nothing wrong with that pick. Vancouver on the other hand passed on both Nylander and Ehlers to draft Virtanen.
Also, what you said really hasn't disproved ED's point at all. Yes they have drafted some good young players RECENTLY, but the whole reason they got into the basement in the first place is because they drafted so terribly for years (when they were competitive) that by the time the Sedins started to decline they had no-one ready to come up and at least ease the scoring burden on them. And even with Vancouver's promising young forwards they now have, they really are pretty barren in defensive prospects - they won't be going anywhere unless they find some pretty quickly.
Also I agree, Anaheim has struggled to draft and develop top 6 forwards - but Anaheim does have 2 young top 6 forwards already on the roster (Rakell and Kase), so it's not like Anaheim is completely barren there. Then between Comtois/Terry/Roy/Jones - they only need 1 of those to hit (in the sense of being a good top 6 forward) to be pretty well stocked for quite a while for top 6 wingers. Center is another situation all together, Anaheim is hoping that Steel can become a #1 down the line (jury is out on that one).
Anaheim really isn't in a terrible position, they have a #1 goaltender, a very good top 4 who are all on the younger side and some good young forwards on the roster, really the only thing they are missing is a high end young center (if Steel develops into a good #2 that is still pretty good for Anaheim) but other then that they have all the pieces to be a solid team for a long time. Can't help but feeling Anaheim's demise is being a little overblown, unless Getzlaf loses both legs in the off-season.
