Context: In 2006-07 NBA season, Jamess averages declined to 27.3 points, 6.7 rebounds, 6 assists, and 1.6 steals per game.

In Game 5 of the NBA Conference Finals, James notched 48 points with 9 rebounds and 7 assists, scoring 29 of Clevelands last 30 points, including the game-winning layup with two seconds left, against the 2006-07 Detroit Pistons season. After the game, play-by-play announcer Marv Albert called the performance "one of the greatest moments in postseason history" and color commentator Steve Kerr described it as "Michael Jordan-esque". In 2012, ESPN ranked the performance the fourth greatest in modern NBA playoff history. The Cavaliers went on to win Game 6 and claim their first-ever Eastern Conference championship, earning them a matchup with the 2006-07 San Antonio Spurs season in the 2007 NBA Finals. During the championship round, James struggled, averaging 22 points, 7.0 rebounds, and 6.8 assists per game on just 35.6 percent shooting, and Cleveland was eliminated in a Whitewash (sport).
