I think they should call offsides more like icing. If you were pretty close, it's not icing. No one is calling back an icing based on an inch here or there. The linesmen don't really care if you were a 1/2 inch behind the red line when you shot it. There isn't video review for icing.
Offsides should be the same. If you were close enough that it looked like it should be on sides, then fine. It is. We don't need to scrutinize skate blades being a fraction of inch this way or that. Who cares.
They don't need to go crazy and allow everything, but they should loosen up the standard. Just let the game flow. It will all even out, there will be more goals and less stoppages.
So much of the game is based on subjective calls from the refs anyway. It's so weird to me that they scrutinize certain rules so much more than others. Offsides? .25 inches over and boom, play over.
Icing? Penalties? Line changes? etc... All called way looser.
