I see. Well, I guess that puts me in the camp of those who think his Heisman should be taken away, but that USC should retain its national titles.
Actually there is a precedence for taking away a NCAA team title for using an ineligible player. In 1999, the UCLA softball team used an Australian player named Tanya Harding (same name as the skater/criminal, hard to believe, but true). She was the Bruin's No. 1 pitcher in a pitcher-dominated sport. UCLA beat Arizona for the NCAA Title. Afterwards, it was found that Harding, who was enrolled for only one semester, had never even attended class at UCLA. The NCAA stripped UCLA of the title, but did not award Arizona with the championship.
