Harrison Barnes goes down with a sprained ankle and here comes Rush, usually an afterthought but suddenly a central character Saturday night at Oracle Arena. [...] did the Warriors' historic start reach 18-0. Curry took only seven shots from the field Saturday night and scored just two points after the first quarter. The Warriors still cruised, with no fewer than six players scoring in double figures. Green became the first Warriors player since Wilt Chamberlain in 1964 to post a triple-double in consecutive games. The Warriors now have won 22 consecutive regular-season games, including their final four to end last season. Golden State also has won 28 consecutive regular-season games at home, the longest home winning streak in franchise history. The Warriors led 56-46 at halftime, and then Rush — who hasn't done much in the NBA since a devastating knee injury in November 2012 — suddenly got hot. Or, for irrefutable evidence of early sluggishness, Curry missed his first two shots from beyond the three-point line. Curry rested for more than six minutes to start the second quarter, a stretch during which Warriors reserves pushed the lead to nine points.
