Richardson attended Broadmoor High School in Baton Rouge, LA, where he starred in both baseball and football.
He played collegiately at Texas A&M and made an immediate impact as a freshman coming off the bench and making his first appearance for the Aggies against Southern Miss and future NFL star Brett Favre, Richardson led the Aggies to a road victory in Jackson when he broke away in the fourth quarter on an 82-yard touchdown.
[1] He played mostly in mop-up duty and even saw action on special teams during his first two seasons in the league, but when Oilers' QB Warren Moon was traded to the Vikings, Houston's quarterback position was up for grabs.
Richardson was the starter for nearly half of the season and he split time with Carlson and Billy Joe Tolliver, none of the three being particularly effective as the Oilers stumbled their way to a league-worst 2–14 record.
Richardson resides in the Houston suburb of Missouri City, Texas with his wife Tracy and their three children.
