The Olympics are bigger—with 9,000 athletes from more than 120 nations—and presumably better this year, reports SI's Munich-bound crew. The U.S. track and field squad, says Pat Putnam, has more youthful confidence (about two-thirds of it belonging to Steve Prefontaine) than ever. Mark Spitz is serene and properly vengeful, according to Jerry Kirshenbaum, and will lead a U.S. swim team chock full of chicks itching to dunk Aussie champ Shane Gould. There is also a portfolio of Olympians from many nations and a complete set of medal predictions. Plus the news of the week in baseball, pro football, horse racing and golf.
