You wouldn't believe it if someone told you a month ago that the Boston Celtics may be a team capable of winning an NBA championship.

There's no arguing that the Celtics' brand of basketball up until the last month of the previous two seasons was unacceptably bad. They were a .500 team for the previous year and a half, and anytime that happens to a Celtics team, everyone starts to wonder what's going on, causing fans to become enraged. Every year that does not result in an NBA title is a disappointment for one of the most legendary teams in NBA history.

Something has clicked for this Celtics squad in the last few weeks. Everyone knew they had the skill to play the way they are, and it's exciting to watch them finally playing the sort of basketball that everyone knows they can.

It won't be easy for the Celtics to win an NBA championship, but they have a decent shot if they keep playing at this high level.

Here are three reasons why the Boston Celtics have a decent chance of winning the Eastern Conference this season.

Winning an NBA title is never easy. As we have seen with the past 20 champions, every team is going to need something significant to go their way. Whether that is an unfortunate injury to someone, or having guys on the roster step up more than they ever have. There is a reason why winning a championship is so hard, and a reason why we have seen crazy upsets in the past. If a team is going to win a title, they’re going to need everyone on their roster to be playing the best basketball they possibly can, and even sometimes that isn’t enough to get the job done.

Celtics Eastern Conference

3. One of the NBA's top defenses

The Boston Celtics have had one of the strongest defenses in the NBA, which is one of the reasons they've had so much success in the last month. Put aside all of the statistics claiming that they have the top defense, which they do, and just look at what they are doing as a team on defense. They were one of those teams that didn't always give it their all on defense, but now that that has changed, they're demonstrating what happens when you defend at a high level.

On that side of the basketball, players like Jayson Tatum, Jaylen Brown, Robert Williams, Marcus Smart, and others have really stepped up for the Celtics, resulting in them being one of the top teams in the NBA.

No matter how good Jayson Tatum and Jaylen Brown are on offense, this team's success will be determined by their ability to continue to defend at a high level. Obviously, the statistics will decrease since they have been the top defensive team in the NBA in terms of stats for the previous month, but it does not mean that their effort should decrease too.

2. Something has finally clicked

Everyone understood what kind of basketball this Boston Celtics team could play, and they just weren't doing it, it was as simple as that. When you look at their roster, you can see that they have more than enough talent to win an NBA title.

Aside from this Celtics team's defense ramping up, there has been something else that has really clicked. It's difficult to pinpoint exactly what has clicked for them, but whatever it is, they must keep doing it. They appear to be having a lot more fun playing together, and that might just be because they're winning games, but everything in Boston appears to be much better than it was a few months ago, and they're hoping to keep it that way for the rest of the year.

1. Jayson Tatum and Jaylen Brown

Because Jayson Tatum and Jaylen Brown are two of the top players in the NBA, the Boston Celtics will be able to win an NBA championship. There's no doubting that both of these players are among the best scorers in the NBA, and if Boston wants to keep winning in the playoffs, they'll have to keep playing excellent defense and rely on Jayson Tatum and Jaylen Brown to be two of the best players on the planet.

Many teams will not want to play against his Boston Celtics squad since each of these players can score 80 points in a single game when they are on their game. This is a team that no one wants to play against when they're both on their game.
