5. 2006-07 San Antonio Spurs – 3

Undrafted players: Bruce Bowen, Jackie Butler, Fabricio Oberto
It doesn't come as a surprise that the San Antonio Spurs have three teams in this list. One was the 2007 championship team.

Undrafted players: Elijah Bryant, Mamadi Diakite, Bryn Forbes, Axel Toupane

Undrafted players: Andrew Gaze, Jaren Jackson, Avery Johnson, Brandon Williams, Gerard King

VanVleet was tremendous during the series, as he averaged 14.0 points, 2.7 rebounds, and 2.2 assists per game to deliver a title to Toronto.
