22. Milwaukee Bucks (2019)
The Bucks were formidable in 2019. They surged through the regular season. From November to December, they enjoyed one of the greatest winning streaks in franchise history. It looked like they were on course for a 60-win season. Reigning MVP Giannis Antetokounmpo had reached a new level. The team was on fire, but then along came the global health crisis.

Their streak lasted for 18 games (via SBNation). The Bucks battled to the postseason but their year fizzled out. After several NBA players tested positive, the league decided to place the playoffs in a bubble. However, Milwaukee didn’t thrive in these circumstances. The Miami Heat destroyed their dreams across a five-game series. Finally, the Bucks crashed out in the Conference semifinals.
