2006: Booty was impressive while starting for his first season at quarterback as a junior in 2006 after serving as USC's backup the previous 3 years. He won the starting job despite missing all but the first day of 2006 spring practice with a herniated disk in his back that required surgery in late March (he was healthy throughout 2006 fall camp). Overall in 2006 while starting all 13 games, he completed 269-of-436 passes (61.7%) for 3,347 yards and 29 TDs with 9 interceptions. He also had 33 carries for minus 53 yards (-1.6) with a TD. He was 14th nationally in total offense (253.4, first in Pac-10) and 24th in passing efficiency (144.0, first in Pac-10). His 269 completions in 2006 was tied for fourth on USC's season passing list. His 3,347 passing yards in 2006 was fifth on the USC season list (15th on the Pac-10 chart), joining Carson Palmer, Rob Johnson and Matt Leinart as the only Trojans to eclipse 3,000 passing yards in a season. His 3,294 yards of total offense in 2006 was fifth on USC's season ladder (15th on the Pac-10 list). His 29 TD passes in 2006 was tied for fourth on the USC season list (tied for ninth on the Pac-10 ladder). He threw a TD pass in 12 of his 13 starts in 2006 (all but UCLA), including 9 games with at least 2 TD throws and 7 with 3 TDs. He threw for at least 200 yards in 11 of USC's games in 2006, including the last 7 in a row.

2005: Booty was USC's No. 2 quarterback as a sophomore in 2005. Overall in 2005 while appearing in 10 games (all but Notre Dame, Fresno State and Texas), he completed 27-of-42 passes (64.3%) for 327 yards and 3 TDs with 2 interceptions. He threw his first career TD pass while hitting 2-of-5 passes while directing USC in the fourth quarter at Hawaii.

2004: Booty was set to be the No. 2 quarterback as a sophomore in 2004. But he suffered a badly bruised right (throwing) elbow in 2004 fall practice, which limited his participation, so he redshirted.

2003: As just a first-year freshman in 2003, Booty emerged as USC's No. 2 quarterback by mid-season. Overall in 2003 while seeing limited backup action in 5 games (Stanford, Notre Dame, Washington, Arizona and UCLA), he completed 7-of-14 passes (50.0%) for 90 yards. He broke his left wrist against UCLA, which sidelined him for USC's last 2 games of 2003. He was 1-of-4 for 13 yards against Stanford in his first action as a Trojan, then hit his only pass attempt (a 5-yarder) at Notre Dame, was 3-of-6 for 63 yards at Arizona and 2-of-3 for 9 yards against UCLA.

High School: As a junior quarterback in 2002 at Evangel Christian Academy in Shreveport (La..), he led his team to the Class 5A state title while throwing for 4,144 yards and 38 touchdowns while earning Student Sports Underclass All-American and Class 5A All-State honors. He also led Evangel Christian to the Class 5A state title as a 2001 sophomore, passing for 4,330 yards and 50 TDs while being named a Student Sports Underclass All-American and Class 5A All-State.

Personal: He's a sociology major at USC.
