The biggest deal of the NBA offseason was the super trade between the Boston Celtics and the Cleveland Cavaliers for Kyrie Irving, and while the point guard is settling into his new home quickly, others might be finding it harder to accept the move has happened.

On Monday night, Irving helped the Celtics achieve a 110-107 victory against the Atlanta Hawks at the Philips Arena in Atlanta, Georgia by going 14-of-22 from the field and posting up a stat line of 35 points, three rebounds, and seven assists.

The point guard is adapting to his new life in Boston well, as he has helped them to a 9-2 record on the season so far, but the same can't be said about the Cavaliers, however, who are trying to adjust to life without the 25-year-old in their ranks.

Cleveland has struggled mightily in the first month of the season, as they currently sit with a 4-6 record, with their defense ranking at the worst in the league. Their most recent game took place on Sunday, and it was a loss to the same Hawks which Boston was able to beat last night.

Minutes after the Celtics game ended on Monday night, LeBron James appeared to drop the biggest message of the NBA season so far, as he posted the Arthur meme on his Instagram with the caption, “Mood…”, which you can see for yourself below.

Many NBA fans are construing this post in one of two ways. The Arthur meme clearly shows that the Cavaliers star is mad about something, but there are disagreements over what exactly.

There are those that believe the post is about Irving after his 35-point performance against the Hawks, and that he has helped the Celtics already achieve their ninth win of the season. Others believe it could be James venting his frustrations with his current teammates in Cleveland.

In truth, it could mean anything, and we may never know the true meaning behind it, but this certainly isn't the first time we have seen passive aggression on social media by the four-time MVP.

James' fellow Cavaliers players Isaiah Thomas and Dwyane Wade seemed to have poked a little fun at him about it though, as Thomas commented on the post, "Need me to handle somebody cuz?" Wade though was far more cryptic, commenting with 14 crying laughing emojis.

Cleveland takes on the Milwaukee Bucks on Tuesday night at Quicken Loans Arena in arguably a must-win game, especially after this Instagram post.
