Kansas University’s banner recruiting class for 2005 had one key position missing out of its first 22 commitments — a running back.

Problem solved.

Commitment No. 23 is a ball carrier, and don’t blink, or you just might miss him as he zooms by.

Super speedster Aaron Brown of Katy, Texas, gave KU his nonbinding oral commitment Thursday, according to rivals.com. It’s another solid pickup in a 2005 class that quickly is moving up the national rankings with each new pledge.

Brown will bring remarkable athleticism to KU this summer. Despite his 6-foot, 200-pound frame, Brown can flat fly, running a 40-yard dash in 4.4 seconds. He also recorded a 10.38-second 100-yard dash time last spring, the fastest time in the nation for sprints with no wind, according to the National Scholastic Sports Foundation.

As much as coaches say you can’t coach speed, Brown will be a welcome addition to KU’s team, led by a coaching staff that often is praised for its knack at developing players.

“He is still raw and has a lot of ability,” Brown’s coach, Joe Sheffy of Mayde Creek High, told Jon Kirby of rivals.com. “He gets better every time he touches the ball. He hits the hole very fast and has good balance. He is one of those kids who doesn’t look like he is running hard, but outruns everybody.”

Brown’s senior year on the football field was cut short by an injury, perhaps contributing to the spotty attention he received from big-name programs. Brown chose KU over Colorado, TCU and Tulsa.

KU’s top three halfbacks — Clark Green, John Randle and Gary Green — all return, so Brown likely would be a strong candidate to wear a red shirt his first year in Lawrence.

Along with KU’s 16 other known high school commitments, Brown — whose hometown is the same as Jayhawk punter Kyle Tucker — can’t sign his letter of intent until the Feb. 2 national-signing day.
