I gotta say, while Rask was a bit of a whiny bitch over the blade loss, I do think the NHL might need to think about a change that rule. The goalie is at a pretty big disadvantage. I think they should address it the same way a down player is ruled - don't blow the whistle if there's when there's active offensive pressure, but as soon as it's relieved, blow the whistle.
He's got to make a better effort to be in some kind of position though.
