The Golden State Warriors built a dynasty based on a mathematical fact so rudimentary it’s obvious to preschoolers: Three points are more than two. This elementary idea catalyzed a revolution—and the analytics of efficient decision-making overtook NBA strategy.

In the NFL, there isn’t one single inefficiency—like the underuse of a 3-point line far away from the basket—to exploit. So as analytics-driven efficiency boomed in the NBA, the NFL experienced no such upheaval.

Then came 2018. The passing game produced more points than at any point in NFL history, and there was one team at the forefront. The Kansas City Chiefs became the Golden State Warriors of football.

The Chiefs, though, didn’t have one idea that would make their offense one of the best in NFL history and the vanguard of a changing league. Instead, the Chiefs and coach Andy Reid produced the highest-scoring offense in a historic season with a series of smaller innovations.

“He does a great job of taking new ideas, new concepts and utilizing them in a productive and efficient way,” said Bill Belichick, whose Patriots face Kansas City in the AFC Championship on Sunday. “They’re hard to stop.”
