School: Rancho Cucamonga High School, Calif.
Chung spent his early years in Jamaica and was a late-comer to football, but he quickly picked up the game, making the high school freshman football team as a 12-year-old.
"We didn't realize how young he was," said Chris Vanduin, who coached Chung at Rancho. "He never shied away from anything, but he was giving up so much weight. At that time he was using his speed. I don't think we treated him like a 12-year-old."
