As a senior Barrett was the Florida Class 8A Player of the year after throwing for 2,018 yards and 20 touchdowns and rushing for 23 scores and 1,413 yards. He led his team to the semi-finals of the state playoffs.
An Under Armour All-American, Barrett elected Auburn over offers from Florida, Alabama, Ohio State and others. As a senior he was a finalist for Florida's Mr. Football Award after leading West Orange High to the most successful season in school history.
