Sources say the Cavaliers are very high on the 20-year-old small forward and appear unlikely to let him slip past them at the No. 4 slot in the June 28 draft. While this week's predraft combine in Chicago (June 6-7), and the team workouts thereafter, could always change things, rival executives are planning for Barnes to be off the board by the time the fifth pick (Sacramento) rolls around. "He's a pretty big deal to them," one such executive said. ... Kansas forward Thomas Robinson could be a good fit alongside third-year center DeMarcus Cousins, but the buzz that Washington will take him at No. 3 remains strong (that is, of course, if Charlotte opts for Kentucky small forward Michael Kidd-Gilchrist at No. 2). It sounds as if the Kings like -- to varying degrees -- Barnes, North Carolina big men Tyler Zeller or John Henson, or even Kentucky forward Terrence Jones more than risky prospects such as Connecticut center Andre Drummond or Baylor forward Perry Jones III.
