Johnson starred as a running back and defensive back for Mesa High School in Arizona. He also played basketball, but really made his mark in football. In his senior season, Johnson totaled 16 offensive touchdowns, 59 tackles, and three interceptions. He ultimately chose to stay in his home state, as he decided to take a scholarship from Arizona State over one from Arizona.
In 2008, Johnson took a redshirt, and spent the year playing with the scout team. The following year, he played in all 12 games, and had one start. He had 11 tackles on the year. Prior to the 2010 campaign, Johnson earned the Hard Hat player recognition for his work in ASU's offseason strength and conditioning program. On the year, he had two starts, 22 tackles, and one interception. In 2011, Johnson played in all 13 games and had three starts. He tallied 48 tackles, 1 sack, and two interceptions on the year. In his redshirt senior year, Johnson finished second on the team with 88 total tackles, and led the team with five interceptions and 13 passes defensed. He was an All-Pac 12 honorable mention.
Future Hall of Famer

A quality player who will contribute to the team early on and is expected to develop into a starter. A reliable player who brings value to the position.
A prospect with the ability to make team as a backup/role player. Needs to be a special teams contributor at applicable positions. Players in the high range of this category might have long-term potential.
A player with solid measurables, intangibles, college achievements, or a developing skill that warrants an opportunity in an NFL camp. In the right situation, he could earn a place on a 53-man roster, but most likely will be a practice squad player or a camp body.
