I absolutely agree that the expectation that we pull a Nashville and pull a high quality defenseman out of basically every 3rd or 4th draft is silly. It's just never going to happen. That said, I think there are two confounding factors going on here: a) we don't/didn't take enough defensemen and b) we took the wrong defensemen. (a) is easy to address, especially when you see that our history on the forward front isn't really all that much better. We're not passing on defensemen to draft Wayne Gretzky. (b) I think is the more important issue: we're not identifying the right guys.
In 2007, in the first round, we took Brendan Smith, the 68th ranked skater in CSS's
list. We passed on Subban, who was ranked 102. Given that it was pick 27 and we were reaching either way, I think that the ranking difference is fairly negligible. But I think we can reasonably assume that our scouts thought Brendan Smith would have a better NHL future than Subban, who went 17 picks later (and still well ahead of his ranking). I think we can call that either a scouting issue or a development issue pretty safely - either Smith wasn't worth that pick and our scouts missed something, or he was and he messed up his development. I'm open to other interpretations, but I don't think "he just wasn't very good" holds much water (not that anyone's saying that, specifically).
Given all of that, I think we can see two things - either we need to revamp the scouting and development program for defensemen, or we need to draft high enough that the chances of hitting a home run are much higher. To address your other point, while I think it does make it look a bit worse to say "here's what the rest of the league did compared to us", I don't think that's the best way to read the list. I think it's better to read it as, "here are the chances we missed on", which should lead to "why did we miss?" Yeah every other team might've only got one guy to match our one Kronwall, but we still missed on 20+ guys. If Holland is really as good a GM as people say, that shouldn't be happening, or if it's happening regularly, it should be getting addressed. If it was, and if we were even finding one top pairing defensemen a
decade, I'm pretty confident that this team would be moving in a very different direction and the 'reload' would be a much better strategy.
