Why It’s Hard to Go Undefeated in a Season?

No matter how good or stacked an NBA team is, it’s impossibly hard for them to go undefeated. As we saw from the stats above, the best team to do it is Golden State Warriors with 73 wins and 9 losses.

But why exactly is it so tough to go undefeated in the NBA? Here are the most probable reasons:

1. There are so many games in a season

Each team plays 82 games in a season. But they may also play up to 28 games in the playoffs.

So, in short, there are just too many games to be played in a span of less than 7 months.

Exhaustion plays a big part in the reason why no NBA team has ever gone undefeated. After all, you can’t expect to play your best every single game night now, can you?

2. Injuries and availability

As a result of playing a lot of games, players will start to feel the tension in their bodies which can result in injuries.

So, when you’re playing the best teams in the world without your full force, you can’t expect to win.

That’s why today’s NBA is a game of availability. No matter how good a team is, the team with the complete force almost always wins.

3. It’s not their priority

The number one priority of every team is to win the finals. The second one is to get to the playoffs at least.

As such, no normal team would make it their priority to win 82 games in a season. They would just be exhausting their players which would be so dangerous come playoff time.

Instead, they try their best every single game and watch their regular season record. As long as they can clinch the playoffs, most teams won’t bother gunning for the 82-0 record.

4. Luck plays some part

The longer the season is, the harder it is to go undefeated. Back then, teams used to play 48-71 games a season. Even then, no NBA team has gone undefeated.

How much more today where there are 82 games in a season not including the playoffs?

So, a good team will have many lucky nights and some off nights where they just can’t get their rhythm.

5. Increasing competition

Basketball is an ever-evolving sport with new moves and rules being implemented every so often.

As such, what was required to win back then may no longer be what’s required today.

In short, teams and players are becoming more competitive which means it’s virtually impossible to go undefeated.

Just imagine, it took 20 years for an NBA team to break the Chicago Bulls best regular season record! And it took four future hall-of-famers in Curry, Thompson, Green and Iguodala to clinch that record.

Not to mention, they only beat the bulls’ record by one win. So, how much more difficult will it be for future teams to beat this new record or even more so going undefeated?


It’s extremely hard to go undefeated in the NBA. Not only is the competition tough, but there are just so many factors in play.

It’s fun to see a team dominate the competition on their way to the finals. But it’s also not bad to see closely matched-up teams beating each other.
