I think people make too big a deal about the D. Yes we need that elite puck mover, but overall the depth is pretty good.
In reality most D cores are signed through free agency or built through trades, unless you're Nashville who draft heavily on D.
Add one elite guy like Chychrun and I'd say we're pretty good. We have the solid bottom pairing projected guys, and I'd say at least a few potential top 4 in Hutton, Corrado, Brisebois, and Subban. The rest can be filled through free agency.
Just need one good draft to address that area.
