Richardson, who possess true top-flight speed -- in the 4.35 range -- chose the Mustangs over offers from Colorado, Arkansas State, and McNeese State, and he is receiving heavy interest from Michigan as well.
The senior from Central High School in Baton Rouge returned several kicks and interceptions for touchdowns this year for the 7-4 Wildcats, who were eliminated in the opening-round of the Class 5A playoffs by New Iberia.
Earlier this year, he had a pick-six against SMU commit Jermaine Sams' team, the St. Paul's Wolves.
Sams, who is helping to recruit Richardson to SMU, mentioned a couple of days ago that Richardson is a fearless corner, "the real deal." Sams went on to brag about Richardson's physical style of play, remarking that Richardson - unlike most corners - isn't afraid to get in a receiver's face with press coverage.
Over the course of his senior season, Richardson collected 60 tackles, four interceptions, and several hundreds of yards on punt and pick returns. He also rushed for several touchdowns and took an 86-yard punt return to paydirt vs. Denham Springs.
