That's one he has to save.
But also it was a tricky shot, deflecting off the stick and making the shot a lot slower which eluded him.
But one thing about Rask i think he has to improve on is plays like these. For some reason i see a lot of goals that deflect off of something scored more on him than anyone else. Rask is very good making a save when he sees it and when its a regular shot without any deflections. But his style seems to be very prone to letting in surprising shots. Not sure why because he's a good positional goalie. Maybe he reacts too early, i dont know.
