Kemba Walker trained with the USA Select team that helped prepare the USA National Team for the world championships in Turkey.

Playing against the likes of Derrick Rose, Russell Westbrook, and Rajon Rondo helped take Walker’s game to new heights.

"The USA thing changed my life," he said. "The way those guys guarded me, nobody guarded me like that in my life. Playing those guys made me realize how good I was on this level. It made me see things slower."
