Vox shows how the 3-point line is “breaking” the game.
The basic math says a 3-point shot is more efficient for scoring points than a 2-point shot if the team can make a high enough percentage of attempts. It’s why the mid-range shot has fallen out of favor.
But it’s more an evolution than a breaking. Defense adapts, and then offense adjusts to that, etc. Stephen Curry making double-digit threes is still way more exciting than Curry not making threes.
