Consider the segment from 1:22 to 1:28 of the video at https://twitter.com/sportsnet/status/1469495840079327233
These events occurred in this order:
- An attacking player A0 is in the attacking zone.
- An attacking player A1 possesses the puck in the neutral zone.
- A1 causes the puck to completely cross the blue line into the attacking zone, without touching it after it has crossed the blue line.
- A0 leaves the attacking zone, causing the attacking team to "tag up" and become onside.
- A1 touches the puck.
If A1 had touched the puck before A0 left the attacking zone, it is clearly offside.
Which of the following rulings is correct?
- There is a delayed offside because A1 did not touch the puck in the attacking zone, but the delayed offside is nullified after the team tags up.
- There is an offside immediately when A1 caused the puck to cross the blue line while his team is offside, just because A1 possessed the puck.
The linesman ruled the first one. The referees ruled the second. The NHL Senior Executive Vice President Colin Campbell later said the first ruling is correct. Who is right?
Also, how is "possession and control" defined? Is simply being the last player to touch the puck enough to be in possession of it? But this would be inconsistent with the fact that shooting the puck across the blue line such that it is far away from the player would create a delayed offside.
