24. 2000-01 Miami Heat
This team was a shell of its former self. After a strong regular season, the Heat were swept in the first round by a Charlotte team that many expected them to beat. Alonzo Mourning's absence due to kidney illness was a major factor.

23. 2018-19 Boston Celtics

15. 1994-95 Orlando Magic
Shaq and a young Penny Hardaway were a dominant force in the East. They made it to the NBA Finals but were swept by the veteran Houston Rockets. The series was a crushing disappointment for a young team on the verge of greatness.

14. 1996-97 Utah Jazz
With Karl Malone's MVP season and John Stockton at the helm, the Jazz were a legitimate championship contender. They made it to the Finals but ran into Michael Jordan and the Bulls, losing a hard-fought series that cemented their place as a great, but not triumphant, team.
