I don't think we are that bad. But I think that partly has to do with the fact that the Canucks haven't really used a high pick on a Dman and bombed aside from Juolevi. Before the Juolevi pick, the last defenseman the Canucks drafted in the first round was Bourdon, who had he lived, would have enjoyed a long NHL career. Allen was a good pick. Ference was kind of out of sight out of mind. He wasn't a good pick but in the grand scheme of things there was a high number of busts after. Before Ference it was Ohlund. Before Ohlund it was Wilson (who like Ference was also out of sight out of mind). You have to go back to Jason Herter for another high pick Dman bust.
Of course there are disappointments along the way but we also drafted Bieksa, Sopel, and Edler along the way. Burke in general is pretty good at acquiring defenseman.
I'm not convinced the bolded was a given. He had all the tools but was extremely reactionary. He was in over his head in the NHL and wasn't very good in the AHL either.
It was a statistical look from 1970 to, I think, 2022. Canucks ranked near the bottom of the league in terms of NHL defencemen drafted based on impact, games played, etc. The biggest issue was the team has historically been okay at drafting mid-tier defencemen but, until Hughes, their best defencemen was Ohlund. Then the late 90s and 2000s it became a defencemen every couple draft would make it to every 5 drafts and now here we are. It's easy to just look at the Canucks and go "hey they ain't so bad" but when you look at the trends for the rest of the league, yes they actually are.
