Those guys were all regarded as can't miss picks, which is why they are in the top 5. Juolevi is not regarded as can't miss. It's even debatable as to whether or not he's the best dman in the draft class, and the second Dman drafted didn't go until #9. I think there's a chance he's a Griffin Reinhart (4), Derrick Pouliot (8), Adam Larsson (4), Erik Gudbranson (3), Luke Schenn (5), Thomas Hickey (4), or even Erik Johnson (1), who is solid, but he was taken instead of Toews or Backstrom.
I do think Benning's scouting is probably his forte, and I think he probably did try to trade down, so I'm not heartbroken about the pick. It's just strange that he didn't take the obvious power forward pick, when he took one with the first pick in the last two drafts, and when dmen have a lesser chance of working out
It's too bad he couldn't have taken a shot at a dman with the 33rd pick, but that was given away in the Gudbranson deal.
