As College Football’s Popularity Expands, So Does Its Champions’ Jewelry

TUSCALOOSA, Ala. — After Alabama’s athletic director suggested last month that if college athletes were paid, many would spend the money on “tattoos and rims,” he clarified the statement as a “frivolous” reference to a recent scandal at another university. “We hope to educate our student-athletes,” he said, “that those are not wise investments.”
