Few moments in sports are as exciting as major upsets. America loves the underdog, and when David slays Goliath, the story lingers in our minds long after the games are played.
Throughout its history, the NBA has seen its share of memorable playoff upsets.
Whether it's an eighth seed beating a No. 1 seed in the first round, or a young and inexperienced team knocking off a defending champion in the NBA Finals, basketball provides some of the best drama in all of sports.

Without further ado, let's look at the 25 biggest postseason upsets in NBA history.
