Green was selected with the 35th overall pick in the 2012 NBA draft by the Golden State Warriors. On July 30, 2012, he signed a three-year, $2.6 million contract with the Warriors. In his NBA debut in the Warriors' season opener on October 31 against the Phoenix Suns, Green played one minute, made one defensive rebound, and committed one foul. Green gradually received more playing time in subsequent games, especially in the wake of injuries to Brandon Rush and Richard Jefferson. After getting only marginal floor time at the beginning of the season, by November 22, Green was playing 15–20 minutes per game, and by December 9, as Green gained a bigger role on the team, the Warriors had won 8 of 10 games. On December 12, Green made the winning layup with 0.9 seconds left in the Warriors' 97–95 win over the defending champion Miami Heat.
