@Hatt94 Here is a better picture of it. You can see the end of his skate is inside the blue-line when the puck crosses. He was offside, no question about it. Keep in mind the back end of the skate blade curls up.
@MisterBander yeah i have seen this, need to see a couple microseconds further. And we are talking millimetres. Very hard to call. NHL, might have been a different outcome.
