his father, Jim Harrick Sr., was the head basketball coach. Not surprisingly, Coaching Principles was a favorite course among players on the Harricks team. Every student in the class received an A. Not long afterward, both Harricks were relieved of their coaching duties.       If it strikes you as disgraceful that Chicago schoolteachers and Uni- versity of Georgia professors will cheat-a teacher, after all, is meant to instill values along with the facts-then the thought of cheating among sumo wrestlers may also be deeply disturbing. In Japan, sumo is not only the national sport but also a repository of the countrys re- ligious, military, and historical emotion. With its purification rituals and its imperial roots, sumo is sacrosanct in a way that American     sports can never be. Indeed, sumo is said to be less about competition than about honor itself. It is true that sports and cheating go hand in hand. Thats because cheating is more common in the face of a bright-line incentive (the line between winning and losing, for instance) than with a murky in- centive. Olympic sprinters and weightlifters, cyclists in the Tour de France, football linemen and baseball sluggers: they have all been shown to swallow whatever pill or powder may give them an edge. It is not only the participants who cheat. Cagey baseball managers try to steal an opponents signs. In the 2002 Winter Olympic figure-skating competition, a French judge and a Russian judge were caught trying to swap votes to make sure their skaters medaled. (The man accused of orchestrating the vote swap, a reputed Russian mob boss named Alimzhan Tokhtakhounov, was also suspected of rigging beauty pag- eants in Moscow.) An athlete who gets caught cheating is generally condemned, but most fans at least appreciate his motive: he wanted so badly to win
