From the beginning of his career, Rodman was known for his defensive hustle, which was later accompanied by his rebounding prowess. In Detroit, he was mainly played as a small forward, and his usual assignment was to neutralize the opponent's best player; Rodman was so versatile that he could guard centers, forwards, or guards equally well and won two NBA Defensive Player of the Year Awards. From 1991 on, he established himself as one of the best rebounders of all time, averaging at least 15 rebounds per game in six of the next seven years. Playing power forward as member of the Spurs and the Bulls, he had a historical outburst in the 1996 NBA Finals: he twice snared 11 offensive rebounds, equalling an all-time NBA record. In addition, he had a career-high 34-rebound game on March 4, 1992. Rodman's rebounding prowess with Detroit and San Antonio was also aided by his decreased attention to defensive positioning and helping teammates on defense. Daly said Rodman was selfish about rebounding, but deemed him a hard worker and coachable. Rodman's defensive intensity returned while with Chicago.
