I watched it again, and I was incorrect on the crosscheck (though that did happen earlier in the sequence). What I know is that if the puck is in the crease, the player can enter the crease (with no contact). Nubes did that, then the scramble ensued. At the end of the day, Voukoun was dry-humping the ice and regardless of Knuble, would not have had a prayer to save that. Given that, I thought Malkin's shot that went to review was a goal. But you can never see the actual puck, so it was a legit call both on the ice and upstairs.
