Disagree? The d prospect depth has improved. The d also is quite young now. Are you one of those still suffering from the loss of Frankie? Or perhaps the Harvard guy?
Personally I think it's a bit meaningless. Benning inherited a defense of Edler, Tanev, Hamhuis, Garrison, Bieksa, Stanton, and Weber, with a modest prospect pool of Corrado, Hutton, and Subban.
Yes our D prospect pool is certainly better, Benning has had 3 drafts to add more players and took a dman 5th overall, but we're still a long ways from having as a good a blueline as we had under Burke/Nonis/Gillis.
The thing is, for all that we like to rag on the Canucks past drafting performances, going back to the 90's we've always been good at two things: developing top 4 dmen and two-way forwards. The scouting staff has been historically brutal at finding scoring forwards, but in those two area's above they've been pretty good.
And on the blueline you only need to dress six starting dmen. A deep and promising D prospect pool is nice, but if you start with a solid group and you can
promote one good player every few years, that's all you really need. Hutton <- Tanev <- Edler <- Beiksa <- etc. These guys were always supplemented with good trades for top 4 guys like Jovo, Salo, Ehrhoff, and Gillis started making some headway with UFA signings. Though of course that one thing we've always been missing and has really hurt our Cup aspirations is an elite Norris caliber guy.
So to sum it up: good D prospect pool (while nice to have) does not equal good NHL blueline, and bad D prospect pool does not equal bad NHL blueline. If you can't have both and had to choose between the two you're much better off with the latter.
