He actually has a teammate in perfect position along the boards.
That said, I'd like to see knocking the net off called as delay of game, regardless of intent. Why's it any different than shooting the puck over the boards? You certainly ought to be able to avoid the net when there's not contact.
I don't think I've ever just skated myself into the net like that. Then again, I don't generally have 400 pounds of muscle bearing down on me, looking to crush me into the boards, either. That might make me cut the corner a little closer.
