It should be Hischier...and honestly, i think J'Accuse injury has actually opened the door to Nico having a real shot at breaking the Barkov hegemony on the award. It's such a hugely reputation-based award. Hence Bergeron basically just owning it forever. But i think within that...Barkov is the heir to that mantle, but Hischier carrying on his elite defensive play while also covering for the loss of Hughes ahead of him offensively, makes him a genuine shot at taking home a Selke in the era of Barkov.
