TORONTO — Masai Ujiri, the president of the Toronto Raptors, had seen enough high-powered offenses to recognize that the N.B.A. had turned into the autobahn. The problem was that his players were still chugging along in a Studebaker.

But that was all about to change.

The Raptors would finally embrace ball movement and the art of spacing. They would rid themselves of their propensity for one-on-one play, which had constipated their half-court sets. They would launch 3-pointers and run the floor while cleansing themselves of their fanatical devotion to midrange jumpers, the low-percentage shots that pain the sport’s growing collection of analytics acolytes as much as the bunt vexes their baseball cousins.

And the Raptors would do it with essentially the same roster that had been gassing up the Studebaker.

“You have to adapt,” Ujiri said in a recent interview.

Toronto is the site of the N.B.A.’s boldest experiment this season. Without shuffling any of their core personnel, the Raptors have sought to reinvent themselves by adopting a free-flowing offense that emphasizes passing, cutting and 3-point shooting.
