Top 10 biggest upsets in NBA history

#8 Cleveland Cavaliers VS Detroit Pistons

LeBron James scored playoff career-high 48 points to win Game 5 against the Pistons

The Detroit Pistons were a seasoned team in 2007, as they had been to two NBA Finals and three Eastern Conference Finals in a span of 3 years.They again faced the Cleveland Cavaliers, this time in the 2007 Conference Finals. The Cavaliers had finished 50-32 for the second straight year and finished off with the second seed.

The series began in a similar fashion as the previous one, with the Pistons winning the first two at home, but the Cavaliers fought back and won game 3 and 4 to tie the series 2-2. With Game 5 back in Detroit, it was clear that the Cavs needed a herculean performance from their star to steal this game on the road. And that is exactly what they got.

LeBron scored 25 straight points for the Cavaliers at one point at the end of the game, and finished with 29 of the Cavaliers’ last 30 points. He was the only Cavaliers player to score a field goal in the final 18 minutes of the game and the only Cavaliers player to score period in the final 13 minutes.

LeBron simply could not be stopped, as he scored a career playoff-high 48 points and single-handedly led the Cavaliers to a 109-107 win and finally a series win at home in game 6. Although LeBron and company got swept by the Spurs in the Finals, the fact that the Cavaliers made the Finals in the first place was pretty impressive in itself.
