By most accounts, the business of college sports appears as healthy as ever. The National Collegiate Athletic Association earns more than $500-million a year from its contract with CBS to televise the men’s basketball tournament — money that helps support hundreds of athletics programs. A record 64 football teams in the NCAA’s top division will receive a financial lift by appearing in a bowl game this season. And corporate sponsors and generous alumni are infusing millions more into athletics programs across the country.
