On offense, Rodman's output was mediocre. He averaged 11.6 points per game in his second season, but his average steadily dropped: in the three championship seasons with the Bulls, he averaged five points per game and connected on less than half of his field goal attempts. His free throw shooting (lifetime average: .584) was considered a big liability: on December 29, 1997, Bubba Wells of the Dallas Mavericks committed six intentional fouls against him in only three minutes, setting the record for the fastest foul out in NBA history. The intention was to force him to attempt free throws, which in theory would mean frequent misses and easy ball possession without giving up too many points. However, this plan backfired, as Rodman hit 9 of the 12 attempts. This was Dallas coach Don Nelson's early version of what would later develop into the famous "Hack-a-Shaq" method that would be implemented against Shaquille O'Neal, Dwight Howard, and other poor free throw shooters.
