On December 18, 2010, following a nine-game suspension Selby joined the 2010–11 Jayhawks, scoring 21 points in 27 minutes and making 5 of 8 three-point shots. While Selby sat out, Kansas led the country in many team statistical categories. As a result of his suspension and later injuries Selby played in only 26 of the teams 38 games and averaged only 14 minutes per game after returning from injury. For the season he averaged 7.9 points and 2.2 assists on 20.4 minutes per game.
Controversy
After choosing to attend Kansas, a report came out stating that Selby had not yet been cleared to play by the NCAA. According to this report, the NCAA had been investigating for months the relationship between Selby and Robert "Bay" Frazier, the business manager for New York Knicks star Carmelo Anthony. Selby had acknowledged a friendship with Anthony in past interviews and spoke of his contact with Frazier in an April story in The New York Times. All three are Baltimore natives. Maeshon Witherspoon, Selby's mother, told The Times that she had known Bay since elementary school and had asked him to serve the role of an adviser during his college recruitment. The Times report said Witherspoon asked Frazier to host Selby's in-home visits with college coaches at his own home and that Frazier attended a KU–Missouri game at Allen Fieldhouse in January 2009. On November 21, 2010, the NCAA made their final ruling on the matter, suspending Selby for nine games, and ordering him to pay $4,607.58, the total of the "improper benefits" received from Frazier, to the charity of his choice.
