The Golden State Warriors are the N.B.A.’s driverless car.
Their coach in Game 1 of the N.B.A. finals, who may or may not be their coach in Game 2, was Mike Brown, an assistant who twice coached their opponent. Their coach for more than half of last season was an assistant, Luke Walton, who later moved 370 miles to the south to oversee the pre-K experience that is the Los Angeles Lakers.
The team’s putative, on-paper head coach is Steve Kerr, who conceived this let’s-have-fun team. He missed more than half of last season and almost all of this year’s playoffs as he has dealt with the aftermath of back surgery in 2015.
