25. Joe Dumars (1989)
Team: Detroit Pistons
Opponent: Los Angeles Lakers
Result: Pistons over Lakers, 4-0
Finals stats: 27.3 PPG, 1.8 RPG, 6.0 APG
While he may now be better known as the guy who built the Pistons' 2004 championship squad (and more infamously passed on Dwyane Wade, Chris Bosh, and Carmelo Anthony in favor of Darko Milicic), Dumars was also a Finals MVP as he led the Pistons past the defending champion Lakers.
A relatively anonymous figure in the backcourt playing next to Isiah Thomas, Dumars busted out in the Finals with an incredible scoring display; he led all players with his 27.3 PPG average, put up 24 points in the first half of Game 2, and put in 17 in a row (and 21 total) during the third quarter of Game 3. His 23 points in Game 4 helped the Pistons finish off a sweep of a hobbled Lakers squad on the road in L.A. and earned Dumars the biggest individual honor of his Hall of Fame career.
