​The King is NOT happy.

The Cleveland Cavaliers are off to a dreadful 4-6 start, with those losses coming from awfully inferior teams. At this point, it doesn't look like it's going to get better for the Cavs unless they make some drastic changes and/or wait for the return of Isaiah Thomas.

Meanwhile, the Boston Celtics are absolutely dominating after starting 0-2 on the year. They've won nine straight ever since, which is now an NBA record, and Kyrie Irving is leading the charge without star Gordon Hayward.

Think LeBron is happy about that? Think again.

That was posted shortly after the Celtics defeated the Hawks 110-107. Kyrie dropped 35 points on 14-of-22 shooting and dished out seven assists. 

Let's just say the Cavs could use that right about now, as the team has proven to fall apart without a stout No. 2 option behind LBJ.

Celtics and Kyrie dominating = LeBron pissed.

This season should be fun.
