Chicago Bulls point guard Derrick Rose says he is two or three weeks ahead of his rehab schedule.  He returned to the basketball court on Wednesday to continue his rehab from knee surgery.  Rose tore the ACL in his left knee on April 28th in Game One of the Eastern Conference quarterfinals against the Philadelphia 76ers.  The reigning league MVP had surgery on May 12th and his recovery timetable was set at eight-to-12 months.  Rose averaged 21.8 points, 7.9 assists and 3.4 rebounds in 39 games last season.
