I see this coming up everywhere right now, even among credible journalists, and I just don't think it's true. I get that his SV% and GAA looked respectable prior to last year, but Minnesota's defense has made his life easier than almost any goalie in the league since he arrived. I don't have the numbers on hand, but he's rarely faced scoring chances from high-danger areas relative to other goalies.
What really kills you is watching the Wild play great in their own end, keeping all the shots to the outside... and seeing a stinker, unscreened shot from the point go straight through Dubnyk. Night after night. That's not something that started last year.
