Lakers vs. Celtics (NBA)

The Lakers–Celtics rivalry owns the NBA record books: 12 Finals meetings and 33 combined championships—the most of any pairing in sports history. Magic vs. Bird in the 1980s revived a league on the brink, boosting TV ratings by 56% over three years. This dynasty duel is fiercer than #6 Michigan–Ohio State in trophy output: the Celtics' 17 titles and Lakers' 17 are tied for most all-time. In 2010, Game 7 drew 28.2 million viewers, the highest NBA Finals rating since 1998. The rivalry also features 11 Hall of Fame players across both franchises, a 25% higher concentration than the average NBA rivalry.
