A Meridian, Mississippi native who grew up in Texas, Bonner was a multi-sport athlete at The Woodlands High School, where he earned national recruiting attention as a cornerback and set a high school relay record in track. After developing through the Stanford program, he transitioned to the professional ranks and has continued to compete at the highest level of American football.
