 A roster spot is open on the United States Olympic men's basketball team because Los Angeles Clippers star forward Kawhi Leonard will not be able to participate in the Paris Olympics, which opened for this version of a dream team July 28th versus Serbia. Kawhi Leonard has been battling inflammation and chronic soreness in his right knee, forced him to miss four of his team's six playoff games this year. The Athletic reports that Boston Celtics guard Derek White Jr. is considered a strong candidate to take Leonard's roster spot. Tonight, the U.S. plays the first of five exhibition games ahead of the Olympics.
