BCS #2 ranked LSU came into the national championship title game 12–1, with their one loss at home to #17 Florida 19–7. Top-ranked Oklahoma was 12–1, with the lone defeat coming at a neutral site in the Big 12 Championship Game against Kansas State 35–7. There was substantial media and fan controversy as to which teams deserved to play in the National Title game. USC was ranked #3 in the BCS standings but #1 by both of the human polls, the ESPN/USA Today Coaches Poll and the AP poll, which made up a portion of the BCS Standings. Southern Cal owned a record of 11–1, with its one loss coming in triple overtime at unranked Cal 34–31.
Once the game commenced, LSU's #1 ranked defense held the country's most prolific offense, which had averaged 45.2 points and 461 yards per game, to 154 total yards (32 in the first half) and just one touchdown until midway though the fourth quarter. The Sooners' Heisman Trophy-winning QB Jason White completed only 13 of his 37 passing attempts for just 102 yards. He was also sacked seven times and intercepted twice. LSU's offense was largely supplied by freshman running back and Sugar Bowl MVP Justin Vincent, who rushed for 117 yards and a touchdown.
As a result, LSU won their second national championship and first since 1958. The majority of the coaches voted LSU National Champions as contractually required by the BCS. There were three dissenting coaches (Ron Turner of Illinois, Mike Bellotti of Oregon and Lou Holtz of South Carolina) who voted USC #1. BCS #3 USC won the Rose Bowl against #4 ranked Michigan and was voted the National Champion in the AP Poll.
