Take for instance the 1985 Finals. In the Celtics’ Game 6 loss, they scored only 100 points, the lowest total for either team in the series. In Game 1, the Celtics had set the benchmark for 3-point shots taking 9 and making 7 (77.8 percent). Both teams focused on creating and taking high-percentage shots, which kept the 3-point attempts much lower than what you see today.

By contrast, in many playoff series this year, even one team cracking 100 is a rarity, and double-digit 3-point attempts (if not makes) are the norm.
