LOS ANGELES -- USC is cleaning house in its tarnished athletic department, throwing out much of what got the school in severe NCAA trouble.

Athletic director Mike Garrett and Reggie Bush's Heisman Trophy are the first two items to go.

In a letter to school supporters Tuesday, incoming USC president Max Nikias said Garrett will be replaced Aug. 3 by Pat Haden, the former Trojans quarterback who became a successful businessman and a member of USC's board of trustees. The school also will return its copy of Bush's trophy to the Heisman Trust, among several measures to disassociate itself from the tainted tailback.

The NCAA cited Garrett's administration for a lack of institutional control while slapping the school with heavy sanctions last month, but Haden believes he can change the culture of a program that has been wildly successful and heavily scrutinized over the past decade.

"We're going to do better," said Haden, also the color analyst on NBC's Notre Dame broadcasts for the past decade. "We have to do better. We don't have any choices here. We stub our toe, there's going to be some problems."

USC was hit with four years of probation, a two-year bowl ban and severe football scholarship restrictions after the NCAA found serious rules violations in the athletic department, primarily around the football and men's basketball teams. Most involved illegal benefits for Bush and O.J. Mayo, the talented basketball player who spent just one season at USC.

Haden said the school's plan to get rid of nearly all references to Bush and Mayo -- right down to scrubbing their images from school murals and removing Bush's No. 5 jersey in its place of honor in the lobby of Heritage Hall -- are all part of the NCAA's directive to disassociate the school from the athletes.

Bush's Heisman has been on display alongside the trophies won by Garrett, O.J. Simpson, Matt Leinart, Carson Palmer, Charles White and Marcus Allen. It was still in place Tuesday, but will be gone by the time students show up on campus next month.

Bush still has his own Heisman Trophy. The Heisman Trophy Trust has not taken any action against Bush or made any request to have him return his copy of the trophy.

Though he doesn't start his new job until Aug. 3, Nikias is already at work reforming the Trojans' image.

"The Trojan Family honors and respects the USC sporting careers of those persons whose actions did not compromise their athletic program or the opportunities of future USC student-athletes," Nikias said.

After pledging support for new football coach Lane Kiffin, Haden said he realizes the enormity of his task in restoring credibility to USC, where the NCAA found numerous violations during the tenures of football coach Pete Carroll and men's hoops coach Tim Floyd. After twice telling Nikias he didn't want to be considered for the job, Haden agreed to take it last week.

"We want to compete ferociously and win in every sport, but we want to do it ethically and within the rules," said Haden, a former Rhodes Scholar who became a venture capitalist after an NFL career with the Los Angeles Rams. "We're going to have a culture of compliance around here. Every meeting is going to start with the No. 1 item as compliance. ... We're going to try to be perfect. When we make mistakes, we're going to fess up, and we're going to try to do better next time."
