Well, I get why. Contrary to the historical exaggerations on this board (both among fans and haters), the Canucks have actually been a decent team now for about half their history. Since Pat Quinn came along, they've hardly been the doormat in the way that NHL conventional wisdom likes to paint them – they have picked in the top 5 all of twice in the two and a half decades since Petr Nedved (Bryan Allen and Sedins in back-to-back seasons)... So picking very high is a rare opportunity and one that the club can't afford to blow in a salary cap era.
It's the same reason that concern was immediately expressed here about going for Luc Bourdon – no disrespect intended – over Anze Kopitar, even though that was only 10th overall (but in a strong draft class). There is good reason to get nervous over "project" type players when a surer thing seems to be sitting there, because you don't know when the next time may arise to pick that high. And recent history shows there is no better way to stock talent on a club. So botching a high pick has a pretty profound implication, especially for a team in need of some turnover.
