HOUSTON — Seven years ago, after a group of venture capitalists bought the Warriors, the franchise adopted a peculiar philosophy: Three-point shooting could be foundational to a championship team. In Friday night's 125-108 rout of the Rockets, a team on pace to break Golden State's record for treys in a season, Golden State reinforced the importance of having stingy perimeter defense. Seven weeks after hitting 14 three-pointers in a double-overtime win over the Warriors, Houston finished just 7-of-35 from beyond the arc. In the third quarter, with the Rockets going 0-of-10 from three-point range, Golden State turned a five-point halftime lead into a 20-point cushion. With its best player laboring, Houston couldn't keep pace with the league's most explosive attack. With his backup, David West, sidelined by a thumb injury, Zaza Pachulia battled through foul trouble to record 10 points, nine rebounds and two steals in 20 minutes.
