Joe Riley was sure he wouldn't be named a Rhodes Scholar. "There's no way I'm getting this," he told his parents, Craig and Becky Riley of Etowah, Tenn., after a dinner with the fellow finalists last week. But it happened. Riley, a senior at the University of Virginia, is among 32 U.S. students -- and only two from the Tennessee/Alabama/Florida district -- chosen as Rhodes Scholars this year.
