The McDonald's All-American Game ( CBS, Saturday, 2 p.m.) is as close as the Golden Arches ever comes to serving hot dogs. Two dozen of the nation's most gifted high school seniors will provide a clinic on playground hoops as well as a preview of NBA All-Star Games to come. In this 20th annual showcase, the Big Mac will be 6'9" Tracy McGrady of Mount Zion Academy in Durham, N.C., who plans to bypass college and take the drive-through lane directly to the NBA. Trivia question: Who holds the record for most points scored (30) in this game? Answer: (Surprise!) Michael Jordan in 1981.
