3. Brooklyn Nets – 2022
The Celtics defeated the Nets in 2022 and progressed in the NBA playoffs. But this was one of the all-time choke jobs. Not necessarily because Boston defeated Brooklyn. After all, they had a great roster and one of the league’s best players in Jayson Tatum (via N.Y. Post).

However, most oddsmakers considered them to be the preseason favorites. In the end, they slumped their way into the playoffs. Kevin Durant failed to deliver as the Nets proved that buying a super team doesn’t always work. They spent a lot of money but didn’t reap the rewards.
