The Milwaukee Bucks have had their most postseason success early in the franchise’s history and recently. In just the team’s third season, it went 12-2 in the playoffs en route to its first NBA championship. Three years later, the team advanced to the Finals again, this time having a challenge on its hands before falling to the Boston Celtics in seven games. That was its last long postseason run until its historic 2020-21 championship season.
