Neither opponent is The Greatest, but unbeaten Larry Holmes, the World Boxing Council champ (the World Boxing Association recognizes Muhammad Ali), may be the best heavyweight extant. Here he defends his title against unbeaten Puerto Rican challenger Osvaldo Ocasio in a 15-rounder from Las Vegas. In the 12-round prelim, Ken Norton meets Earnie Shavers, who shook Ali in a 1977 bout.
