Over in the comments of an earlier post about the 1990s Knicks, a discussion is raging about who the best player on the 1995 Houston Rockets was — Hakeem Olajuwon, or his old college teammate Clyde Drexler? At the core of the back-and-forth is whether Drexler’s 120.1 offensive rating (using 23.8% of Houston’s possessions when on the court) was more vital to the offense than Hakeem’s 109.8 ORtg (using 34.1% of possessions when in the game)… In other words, the old usage-efficiency debate. On one side, Drexler clearly contributed more points per possession to the Rockets’ effort than Olajuwon — but on the other side, Hakeem had to create offense on a significantly higher % of the Rockets’ possessions than Clyde, and if you subscribe to “skill curve” theory, this means Clyde’s ORtg was artificially enhanced by the extra defensive attention Hakeem drew — as well as the fact that his shot selection didn’t have to include the offense’s toughest shots, which were presumably going to Hakeem (at least in a larger proportion), in turn dragging down Hakeem’s ORtg.
