New USC athletic director Pat Haden says Reggie Bush apologized to him and expressed regret in a phone call last week. "He's really contrite," Haden said, according to USA Today. "He knows he made a series of mistakes. It wasn't just one mistake. It was a series of mistakes." Bush, a running back for the Saints, has not been stripped of the Heisman Trophy he won in 2005, though USC has returned Bush's Heisman given to the school. Two trophies are awarded for each recipient.
