The coaches who presided over the alleged misdeeds -- football's Pete Carroll and basketball's Tim Floyd -- left USC in the past year.

The penalties include the loss of 30 football scholarships over three years and vacating 14 victories in which Bush played from December 2004 through the 2005 season.

USC beat Oklahoma in the BCS title game on Jan. 4, 2005, and won 12 games during Bush's Heisman-winning 2005 season, which ended with a loss to Texas in the 2006 BCS title game.

The BCS is likely to force Southern California to vacate its national championship. BCS executive director Bill Hancock says in a statement Thursday that the presidential oversight committee will meet soon to discuss whether USC will be stripped of its title.

If that happens, there will be no BCS champion for the 2004-05 season. Hancock said no action would be taken by the BCS until the appeal is heard.

The NCAA says Bush received lavish gifts from two fledgling sports marketers hoping to sign him. The men paid for everything from hotel stays and a rent-free home where Bush's family apparently lived to a limousine and a new suit when he accepted his Heisman in New York in December 2005.

The NCAA found that Bush, identified as a "former football student-athlete," was ineligible beginning at least by December 2004, a ruling that could open discussion on the revocation of the New Orleans Saints star's Heisman. Members of the Heisman Trust have said they might review Bush's award if he was ruled ineligible by the NCAA.

"The Heisman Trophy Trust will have a comment at the appropriate time," the group said in a statement. "Until that time, it will have no comment."

The rulings are a sharp repudiation of the Trojans' decade of stunning football success under Carroll, who won seven straight Pac-10 titles and two national championships before leaving for the NFL's Seattle Seahawks last January. Floyd resigned last June, shortly after he was accused of giving cash to a middleman who helped steer Mayo to USC.

"I have a great love for the University of Southern California and I very much regret the turn that this matter has taken, not only for USC, but for the fans and players," Bush said in a statement.

"I am disappointed by [Thursday's] decision and disagree with the NCAA's findings. If the University decides to appeal, I will continue to cooperate with the NCAA and USC, as I did during the investigation. In the meantime, I will continue to focus on making a positive impact for the University and for the community where I live."

Carroll says he's "absolutely shocked and disappointed" by the NCAA sanctions imposed on his former Trojans for improprieties surrounding Bush.

The new coach of the Seattle Seahawks said in a video produced Thursday at team headquarters that "the agenda of the NCAA's infractions committee took them beyond the facts."

USC plans to appeal some of the penalties it believes are excessive.

"There is a systemic problem facing college athletes today: unscrupulous sports agents and sports marketers," Todd Dickey, USC's senior vice president for administration, said in a statement. "The question is how do we identify them and keep them away from our student-athletes?"

First-year football coach Lane Kiffin said: "There is some guilt in some penalties, but the punishment is too severe and that's why the appeal process is taking place."

The NCAA took no further action against the men's basketball team, which had already banned itself from postseason play last spring and vacated its wins from Mayo's season.

Second-year basketball coach Kevin O'Neill said he was glad the NCAA didn't impose further punishment on his program.

"I applaud them on realizing self-imposing was our way of saying, 'You know what, we did make some mistakes along the way and what we better do is be vigilant in our efforts,' which we will," he said on campus.

Floyd, who is coaching at UTEP, quit last June, after he was accused of giving $1,000 in cash to Rodney Guillory who helped steer Mayo to USC.

"As Coach has wanted to say publicly for a long time, 'It didn't happen,'" Floyd attorney Jim Darnell said in a statement.

Under Floyd, the Trojans made three consecutive NCAA tournament appearances and had three straight 20-win seasons.

As part of its self-imposed punishment, USC will return to the NCAA the money it received through the Pac-10 for playing in the 2008 NCAA tournament. The Trojans lost one scholarship for last season and one for next season; they lost one coach to off-campus recruiting this summer; and lose 20 recruiting days for next season. USC also vacated its 21 victories during the 2007-08 season, when Mayo competed while ineligible.

"We can't control people 24 hours a day," said O'Neill whn asked about a lack of institutional control at a booster gathering on Thursday evening. "That's all there is to it. You cannot control people from the outside. You cannot control agents. You cannot control runners. Those kinds of things get away from you sometimes because you have no way of knowing. I do know this. We do the right thing every single day by the university, by the athletic department, by the student-athletes."

The women's tennis team also was cited in the report for unauthorized phone calls made by a former player, but the NCAA accepted USC's earlier vacation of its wins between November 2006 and May 2009.

"The general campus environment surrounding the violations troubled the committee," the report said.

The report also condemned the star treatment afforded to Bush and Mayo, saying USC's oversight of its top athletes ran contrary to the fundamental principles of amateur sports.

"Elite athletes in high profile sports with obvious great future earnings potential may see themselves as something apart from other student-athletes and the general student population," the NCAA report said. "Institutions need to assure that their treatment on campus does not feed into such a perception."

USC athletic director Mike Garrett, speaking at a previously scheduled USC Coaches' Tour at the Airport Marriott in Burlingame, Calif., had this to say to boosters: "As I read the decision by the NCAA, all I could get out of all of this was ... I read between the lines, and there was nothing but a lot of envy, and they wish they all were Trojans."

USC's saga reached its climax on a tumultuous day in college athletics, when Colorado's defection to the Pac-10 from the Big 12 provided the first steps in what could be a radical nationwide conference realignment threatening to change the nature of amateur sports.

While the bowl ban is the most damaging to Kiffin, who will have to ratchet up his formidable recruiting skills to tempt players with no hope of postseason play before 2012, USC also will lose 30 scholarships over a three-year period, 10 annually from 2011 to '13.
