Top 10 biggest upsets in NBA history

#3 Boston Celtics VS Los Angeles Lakers (1968-1969)

The aging Boston Celtics defeat the formidable trio of the Los Angeles Lakers

An aging Boston Celtics, led by the legendary Bill Russell in his final NBA season, were in stark contrast to the Lakers who were stacked with star power, that included the formidable trio of stars, including Jerry West, Wilt Chamberlain and Elgin Baylor.

The Celtics made the playoffs as the fourth place team in the Eastern Division, with a regular season winning percentage of 58% and weren’t even favoured to reach the Finals.

In the Finals, Boston shut down two of the Lakers’ big three, Chamberlain and Baylor, and held Lakers powerful offence in check. Chamberlain who averaged 20.5 points in the regular season was reduced to 11.7 points per game in the Finals, and Baylor from 24.8 to 18. This Celtics finals victory, the last championship of the Bill Russell’s dynasty, is considered as one of the biggest upsets in NBA history.

This Finals is also known for the fact that, for the first and only time in NBA history, the Finals MVP went to one of the players from the losing team. That player was none other than 'The Logo' Jerry West, who averaged nearly 38 points per game during the Finals and was awarded the Finals MVP for his spectacular performance.
