Richardson, a 5-8, 150-pound floor general, said he picked coach Barry Collier's Huskers over Wyoming, Florida State and Mississippi State.
"The Big 12 is the No. 1 conference in the nation," he explained, "and there's a great possibility I can go there and play right away. Their point guard right now is a senior. I feel at home there. I fit in."
Richardson is small in size but big on skill and leadership. He's a high-energy player who's a tremendous passer and a ferocious on-the-ball defender.
He averaged 10 points, eight assists, seven steals and five rebounds a game last season for perennial Chicagoland prep power Proviso East.
Also in last year's high-powered backcourt on that squad? McDonald's All-American Dee Brown (now a freshman point at Illinois) as well as likely 2003 Mickey-D's honoree Shannon Brown (a Michigan State commitment).
Richardson helped PEHS to a quarterfinal berth in July's And1 High School National Championships and traveled the spring and summer circuit with Larry Butler's Illinois Warriors.
