20. Indiana Pacers – 2003
Many people believe that the Pacers wasted a massive opportunity in 2003 when they fell short against the Celtics. A highly-favored Indiana side met Boston in the first round but lost a six-game series. It was a shock because the Pacers had an exciting roster full of stars.

The following season they threw away another great chance when the Malice at the Palace kicked off. Many of their best players suffered suspensions and that was it for the team. There are a lot of what-ifs about this edition of the Pacers but we’ll never know (via The Game Haus).
