Yahoo! Sports says a federal investigation into extortion claims by former USC tailback Reggie Bush has revealed the existence of taped conversations that could confirm Bush took cash and gifts while he was playing at USC. If proven true, what does this mean to USC? The NCAA would have to show USC either knew or should have known about the alleged wrongdoings. At the moment, that's a longshot. Now if somebody can upload the tapes to the Internet, please let us know. We'd be happy to link to them.
