With the Warriors on the brink of elimination, head coach Steve Kerr used Wednesday's media session as a chance to issue an all-points bulletin on center Andrew Bogut. The Warriors trail the Thunder 3-1 in the Western Conference finals — a best-of-seven series that is being decided by effort, rebounds and defense. The Warriors have chosen to dare Andre Roberson to beat them, and the Oklahoma City shooting guard is doing it. With the Warriors sagging off the third-year player to double-team Russell Westbrook or Kevin Durant, Roberson is averaging 15 points, nine rebounds and three steals in the past two games. The Warriors used the strategy successfully in Game 2, which they won by 27 points as Roberson missed three of his five shots, scored five points and played just 15 minutes. Draymond Green joined Nate Thurmond as the only players in Warriors history to earn multiple NBA All-Defensive first-team honors. Oklahoma City center Steven Adams said he didn't wear an athletic supporter in Game 4, despite taking hits to the groin in back-to-back games. [...] time is a coincidence. [...] time is a trend, Adams said.
