In an upcoming book, a would-be San Diego sports' marketer provides new details regarding allegations that he gave Reggie Bush tens of thousands in cash while Bush was still at USC. "Tarnished Heisman" shifts much of the focus from Bush's parents -- who also allegedly received benefits -- to the star running back. However, while the book hints that USC coaches may have known about some of the arrangements, it does not provide evidence that any school official was aware of alleged improper gifts. Based largely on interviews with Lloyd Lake, who tried to secure Bush as a client for the marketing company he and others attempted to launch, the book claims the 2005 Heisman Trophy winner was provided with hotel stays, cash for shopping sprees, and money to buy and customize a car. It also contains transcripts of secretly recorded conversations that Lake claimed to have had separately with Bush and his stepfather LaMar Griffin. Bush has repeatedly denied any wrongdoing. His attorney David Cornwell could not be reached for comment.
