College basketball’s two brightest stars were scheduled to workout head-to-head Thursday for the Kings. It would have been a valuable comparison for the Kings, who have the seventh pick in the Draft. But Walker’s agent must have concluded that Kemba has nothing to gain: “Earlier this week, it was reported that Kemba Walker would be working out against Jimmer Fredette in Sacramento for the Kings next week. That workout will be Thursday, June 9, a source told But there’s only one problem: Kemba Walker won’t be there. Walker has pulled out of his scheduled Kings workout against Fredette, a source told The workout will still go on as planned on Thursday with Fredette and a group of other players.”
