"We need to be really structured in how we’re doing it and what we’re putting on all of their plates mentally and physically so that they can have success," Sarkisian said. "We’ve traditionally always thrown our freshmen in there Day One with the ones to see how they respond just emotionally — the guys who have the big eyes and the guys that really love to compete and just feel comfortable and then we start getting information on them."
Jackson was ranked the No. 3 cornerback in the 2014 class by Scout.com.
Last season, while earning California Mr. Football honors, Jackson played running back, lined up at wide receiver, punter, punt returner, and cornerback for Serra high school.
He signed with USC with a buzz around him similar to former Serra star and USC Trojan Robert Woods, although his athleticism has drawn comparisons to that of Marqise Lee.
Like Lee, Jackson played football, basketball, and competed in track and field. This spring he’s attempting to jump 27 feet as he eyes the 2016 Rio Games with hopes of competing in the long jump.
