You listed overall defensive rank. I read somewhere (not sure where) That if you filter by team passing defense, it swings a little more in Josh's favor.
Who gives a sh!t what either has done to this point in the NHL? A 22 and 23 YO shouldn't be expected to have done anything in the NHL unless it's with a completely dysfunctional franchise.
They are both poised to to be completely useful NHL players.
