Earl Campbell was a professional american football running back for Houston Oilers back before they became the Texans. He has trained himself to try to fix his disorder. He told people that he had a panic disorder and that could have probably affected the way he played. Back then i doubt that he would have been treated badly considering how big of a star he was, but if he wasn't a star he probably would not have been treated any different because having a panic disorder isn't as bad as having a serious disability. If he would be growing up today to be a professional athlete he would not be treated differently.
