SACRAMENTO — DeMarcus Cousins has agreed to a one-year, $5.3 million contract with the Warriors, league sources have confirmed with The Chronicle. ESPN was first to report the news. That Golden State added one of the league's best big men with the mid-level exception is further proof of the allure of chasing championships. In 48 games with the Pelicans last season, Cousins averaged 25.2 points, 12.9 rebounds and 5.4 assists. He shot 47 percent from the field and 35.4 percent from three-point range. Unfortunately for New Orleans, Cousins sustained a season-ending Achilles tendon injury on Jan. 26 against Houston.
