Maybe my memory is wrong, but we really didn't have 1 center in the pipeline when Dach was drafted, so I'd disagree that center wasn't a more pressing need over D, at that time, necessarily. Hayden was a bust by then and couldn't crack the top-six. Schmaltz was gone (for Strome) before that draft at the deadline. You pretty much had Kahun and Kampf, who were never slated to be anything special. On D, at the time, you at least had the Joker and Forsling, over just Strome; and Strome was 22 at the time (as was Forsling, but I digress). Bowman, in his great powerful wisdom, would trade Joker a few weeks later, but at the time Dach was drafted, Joker was technically still in the pipeline (and should have been retained).
Anyways, my point is this: if you want to say we were equally dry at both D and C, I'd agree; but if you're saying we were more dry at D than center, I'd disagree, because we at least had Joker at the time. The hope was still there that he could be a legit player when he was traded and he was still very young. Both positions are critical to draft for.
