One of the pleasures of the N.B.A. playoffs is watching talented but complicated basketball teams continue to become who they are. The four remaining teams this year—Thunder, Warriors, Raptors, Cavaliers—have trudged or glided through level after level, inching their way toward the video-game boss that is the Finals. In doing so, two of them have undergone—and continue to undergo—a process of distillation: their characters keep clarifying. The other two, for better or worse, keep showing us who they’ve been since November.
