OAKLAND, Calif. —The Nuggets were there and then they were gone, disappearing under a snowfall of golden confetti. The Warriors won 92-88 on Thursday night, closing out Denver in Game 6 of their first-round Western Conference playoff series. "We didn't lose this series tonight. This was a proud loss," Nuggets coach George Karl said. "This series was lost in Games 1 and 2. ... And that's on me."
