I agree with this.
There's some nuance to this that I think makes it difficult. It will have to be at the referee's discretion just like icing and faceoff violations.
If a dman is retreating with the puck because of active pressure...what's the expectation there? Are they allowed the cross the red line or do they have to dump or give it up or...?
And if you make a pass from the far blueline to just past the redline but you have no play and are under pressure...what then? Or you're in your offensive zone, you throw it up the boards hoping for the pointman but he misses and it trickles down the ice past the blue line and red line. I mean, I think the idea is "the player can't casually carry the puck back over the red line" but when you start thinking through some scenarios, again, you discover a lot of nuance.
I get the idea and what they are trying to eliminate, though. We all know the issue, we've all been frustrated at some point, but developing strict rules that have to apply over a broad spectrum of fluid gameplay is tough. Unless you want to implement a VERY strict rule - once past the red line, you can't carry or pass it or "possess" it back over. Otherwise, it's a whistle and then a DoG penalty. Then you throw every nuance into the bag of "well tough shit". That would also be fine, lol.
