I kind of love the NHL rulebook.
I don’t love everything in it, and I certainly don’t always love the way it’s called, especially when my team is playing. But I’ve always been fascinated by this document that’s existed for a century while being subject to constant tinkering, with brand-new rules living alongside ones that have sat untouched for decades.
Unless you’re an NHL official, you’ve probably never bothered to read through the thing. But you should, because it’s packed with oddities and loopholes and sub-loopholes. I get into some of them in my book, like the rule that can force the players to officiate their own game, and I’ve written over the years about some of the weird exceptions most fans don’t know, like how a goalie can still play the puck outside of the trapezoid if he keeps one foot in the crease.
