Lewis attended Pickerington High School Central in Pickerington, Ohio. He became a star football player at the school and he earned scholarship offers from 17 Division I schools. During his senior year in 2012, Lewis was charged with two counts of rape. It was alleged that he raped a classmate in the basement of another classmate's house on December 2, 2011. The second charge alleged that Lewis raped the same classmate again in the back seat of her car on January 6, 2012. A jury acquitted Lewis of the first charge and deadlocked on the second charge, resulting in the judge declaring a mistrial. Lewis avoided a retrial by pleading guilty to making false statements to Pickerington police. The guilty plea to falsification resulted in the rape charge being dismissed. Lewis was sentenced to three years on probation. Afterwards, he opted to attend Jireh Preparatory Academy, a post-high-school college-prep school in Matthews, North Carolina.
