According to Baylor regents and other administrators, its athletics department avoided random drug testing because of the university's overall strict policy against marijuana use, in which one reported incident might lead to suspension for a semester and a second incident could result in expulsion. Since the university's strict conduct code might derail a student-athlete's career, athletics department officials didn't think it was fair to subject them to random testing.
"What was really happening was the underlying message to them is, 'Hey, the rules don't apply to you,'" one regent said in the book. "You know, and they have been hearing that since the seventh grade anyway. Some rules do apply to everybody, and telling them they don't apply is not calculated to make them productive citizens."
