He's had to be better in this series. It's not quite fair that the only reason this team can win even another game here is through Hellebuyck heroics, but with the injuries and the lack of production of the other big names on the team, he does have to be at what he normally is through out the season.
That said, I find the criticism that he's letting the team down because he's not dragging the team into the next round on his own to be pretty funny.
As a side note, I'm sure the data exists, but I'd love to see how many high danger chances he faces compared to other goalies. He is consistently in the top 5 for goals saved above expected, so I'd have to imagine it's a lot more than most.
