Why did USC vacated national championship?
On June 10, 2010, USC was forced to vacate its two final wins from the 2004 season (December 2004 against UCLA and the BCS championship game), as well as all wins from the 2005 season, following an NCAA investigation into possible violations by the Trojans’ football and men’s basketball programs.
Did USC forfeit their national championship?
Stemming from an NCAA ruling that former USC running back Reggie Bush was ineligible, the BCS officially vacated the Trojans’ 2004 National Championship. This was an expected result, especially since it’s been nearly a year since the NCAA ruled Bush ineligible and USC would have to vacate 14 wins from 2004 and 2005.
