The Nets started the 2009–10 season going 0-18, the worst start to a season in NBA history. Because of their start the Nets fired head coach Lawrence Frank. The Nets won their first game on December 4, 2009 against the Charlotte Bobcats 97-91. Lopez contributed in the win with 31 points and 14 rebounds. In his second season, Lopez established career bests in minutes played per game (36.9) and rebounds per game (8.6) while averaging 18.8 points per game. Lopez started in all the Nets' games in the 2009–10 season. Despite his improving play, however, the Nets struggled all season, finishing with one of the worst records in NBA history at 12-70; only 3 more wins than the 1972–73 Philadelphia 76ers.
