For how much emphasis the NHL puts on this, the fact they still often lack good camera angles in a lot of arena is annoying af. Seriously how hard is it to puck a camera on the roof at both bluelines? Unobstructed overhead views, where there's no angles you're trying to look past.
But also, the fact that this became such a point of emphasis shows the NHL lost the plot on this.
It was designed to prevent the clear-as-day offsides, not the "well he was a mouse's dick over the line, so it's coming back."
Set it up so there's a 1 minute review limit, where they can pause, but not zoom in on the replays. If it's not clear after that, then it's a good goal.
