In his NBA debut in the Warriors' season opener on October 31, 2012, against the Phoenix Suns, Green played one minute. 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, 2012, Green was playing 15–20 minutes per game.

It is not clear how Green's minutes increased over time beyond November 22, 2012 based on the provided text.
