Matt Duschene's goal from a few years ago.

I believe that this was the type of missed call that precipitated the rule change.
And, of course, once you introduce a rule to allow the review of the play, it doesn't matter how offside the player is. Whether it's an inch or a couple of feet, offside is offside and goals are going to be disallowed.
One change to the rule that I would like to see is to limit the amount of time that the linesmen get to look at the replays. If they can't decide within a minute, then it's too close to call and the ruling on the ice should stand. I wanna watch hockey, not the linesmen staring at an ipad. IMO
