"He's a jet," Kansas coach Bill Self said in a media release. "Frank is a really, really quick guard. He's a true point. He can get guys easy baskets. He can break people down, very similar to the way the fans saw Sherron (Collins) break people down off the bounce."
Kansas has signed five to the class of 2013 during the fall signing period so far.
