True story – I once made a comment about this very rule in a gamethread in a hockey subreddit and I think it was one of my most downvoted comments maybe ever. You should get a delay of game penalty if you sit in the trapezoid with the puck not moving for more than 3-5 seconds. I get it’s useful for line changes and maybe that’s not quite enough time, but my god is it boring just watching someone play chicken with a defender or two by standing around in the trapezoid not doing anything at all while both teams do the slowest line changes ever seen. It’s not fun to watch as a fan and it takes some of the chaos and strategy out of line changes. Soccer has a rule where the keeper can only hold the ball for 10 seconds and the players there have a ton of ground to cover and aren’t on skates. This isn’t some weird childhood game of freeze tag. If you’re going to just stand there indefinitely with the puck while nothing happens around you, you should go to the sin bin for it.
