from Kerry Fraser of TSN,

While it "appears" that Kyle Turris' shot "quite possibly" crossed the goal line based on the heel position of Nicklas Grossmann's skate, various angles of video do not provide the necessary conclusive evidence to overturn referee Paul Devorski's initial call on the play and allow a goal.

While it is more probable than not that the puck crossed the goal line, the fuzzy depth perception that we gain once the puck deflected off Grossmann's left skate and went airborne provides a lack of conclusive evidence that is required to allow a goal through video review. The men in the NHL's Situation Room cannot make their decision based on any "logical assumptions" but must clearly see the puck enter the net. Even with various camera angles that are available, that process is made much more difficult once the puck leaves the ice surface and takes flight.
