From TributeToTroy

From the start of training camp, the motto for the 2004 USC football team was "Leave No Doubt." The Trojans did just that, winning their second consecutive national championship. And, unlike 2003, this title was undisputed, as USC demolished Oklahoma in the BCS Championship Game in the 2005 Orange Bowl, 55-19. Troy went 13-0 overall (a school record for victories) and became just the second team ever to hold the AP No. 1 ranking from pre-season through the entire campaign. It was only the 10th time that a team won back-to-back AP crowns. At 8-0, USC won its third consecutive Pac-10 title. The Trojans swept traditional rivals UCLA and Notre Dame for an unprecedented third year in a row.

Pete Carroll's Trojans concluded the season riding a 22-game winning streak, as well as 21 straight home games, a Pac-10 record 15 consecutive league home games, 15 straight Pac-10 games and 9 road games in a row.

Troy was in the national Top 10 in every defensive statistical category (its total defense average was USC’s lowest in 15 years), including first in rushing defense and turnover margin and third in scoring defense. USC outscored opponents by 25.2 points (including a school-record 8 games with a margin of at least 30 points). USC played before 3 home sellouts, 7 regular-season sellouts and 8 season sellouts, all school marks. And Troy set a USC and Pac-10 record for home attendance average, as well as school records for total home attendance, overall attendance average and total overall attendance.

A school-record 6 Trojans (Heisman Trophy quarterback Matt Leinart, Heisman finalist tailback Reggie Bush, defensive linemen Shaun Cody and Mike Patterson, and linebackers Matt Grootegoed and Lofa Tatupu) were named All-American first teamers. Leinart and Bush were named the Pac-10 Co-Offensive Players of the Year, while Cody was the Pac-10 Co-Defensive Player of the Year.
