OAKLAND, Calif. — Kevin Durant gets his ankles retaped. Zaza Pachulia changes into a fresh jersey. Draymond Green removes his sneakers. Some of the players even check their phones, because of course they do.

The Golden State Warriors do a lot of mundane stuff at halftime.

Yet what happens next is extraordinary. Their explosive third-quarter runs have become a phenomenon, and nobody knows quite what to make of it. The players themselves are mystified.

“I honestly have no idea,” Stephen Curry said.

We are not about to solve that riddle, either. Entering Game 1 of the N.B.A. finals on Thursday night, the Warriors had outscored their opponents by an unprecedented 130 points in the third quarter this postseason. It defies easy description. But a closer examination of their halftime rituals may provide some illumination.

The 15 minutes between the end of the second quarter and start of the third are a carefully choreographed production, featuring clips of game footage, wardrobe changes and managerial strategies straight out of business school. Coach Steve Kerr, based on interviews with players and coaches, has worked to create an environment of inclusion. This is not a place for Lombardi-esque rah-rah speeches. Rather, the Warriors’ halftime locker room is a high-speed 360-degree team review.
