It has to be a planar rule. Behind the blue or in front is the criteria, not on the ice and behind. At least as far as I understand the point of the rule.

Why? The NFL has a similar rule on the sidelines. The feet have to be inbounds and on the ground for the player to be considered inbounds. It's the exact same concept. The skate has to be on the ice and not over the line to stay onside. It's not a difficult concept..and has been such for a long long time. This is why players instinctively drag their feet at the blue line on a rush to make sure they don't go offside. Also if u turn it into a plane, when a player tries to keep the puck in the zone their position on the ice determines if the puckstays in the zone. For example. You cannot have both feet on the outside of the zone and use ur hand to keep it in. In this case u are fully out of the zone and even if u reach inside the plane and knock a high puck down it's offside. If u change the rule to what everyone wants to in order to make Forsbergs play onside (something he did to himself btw...he could have put his front foot ON the blue line) then we r gonna have poop show of other examples of offside review that are just garbage.
