Freshman Matt Barkley was named Southern California's starting quarterback on Thursday.
With an outstanding performance at training camp, Barkley beat out sophomore Aaron Corp to get the start in the Trojans' season opener.
"He has exceeded all our expectations," Carroll said in a statement. "He has all the physical ability. He has the mentality and temperament to handle the position. His personality is very well received by all the players, and he's extremely talented. At this point, he's ready to be the guy for us."
Barkley was perhaps the nation's most sought-after football recruit last year at Orange County's Mater Dei High School. After choosing the Trojans, Barkley graduated from high school one semester early to participate in spring practice.
Aaron Corp, in his third year at USC, was named the Trojans' starter out of spring ball, but Barkley took advantage when Corp missed two weeks of workouts this month after breaking a small bone below his left knee Aug. 10.
Barkley is the first non-redshirt freshman quarterback to be picked to start a season opener for the Trojans.
"He's the starting quarterback at USC — it's not a one-game deal," Carroll said. "He seized the opportunity that was in front of him and took control. He deserves all the credit in the world, and we expect nothing but great things from him."
Barkley also beat out Mitch Mustain, the former Arkansas starter who played eight games as Mark Sanchez's backup last season. Sanchez, now the New York Jets' starting quarterback, left USC with a year of eligibility remaining.
Now Barkley must shoulder the enormous expectations of his position at USC. He's following nearly a decade of outstanding college quarterbacks, including Heisman Trophy winners Carson Palmer and Matt Leinart, along with John David Booty and Mark Sanchez.
USC opens the run for its eighth consecutive Pac-10 title next weekend but Barkley's ultimate early test: a trip to Columbus to face No. 6 Ohio State.
