Another roster update for NBA 2K12 arrived this morning and delivers Bismack Biyombo, the seventh overall pick from the draft by the Charlotte Bobcats and rated a low 55 overall, thus completing the first round of rookies. Peja Stojakovic has also been removed after announcing his retirement. That is about the extent of the changes as no additional progress has been made on second rounders and the Rockets signing of Samuel Dalembert hasn’t become official yet.
