Smith attended Banning High School in Banning, California, where he was a three-sport star in football, basketball and track. He played as a safety, quarterback and punter for the Banning Broncos football team. As a senior, he had 109 tackles and six interceptions on defense, while also rushing for 1,579 yards with 13 touchdowns on offense. He was a standout on his basketball team, averaging more than 17 points per game. Also an outstanding track & field athlete, Smith was one of the state's top long jumpers. At the 2010 CIF-SS Division 3 Meet, he posted the top-qualifying mark in the long jump at 7.13 meters, but he had his result stripped by the head official. Smith’s marks would have likely won the meet since the winner of the event posted marks lower than both of Smith’s efforts. Smith was regarded as a three-star recruit by both Rivals.com and Scout.com. He was ranked as the No. 83 overall player and the No. 35 in his position in the state of California. He chose Fresno State over scholarship offers from Nebraska, San Diego State, and UNLV, among others.
