The Knicks are struggling again. After starting off the new year hot, they've dropped five games in a row and are, once again, slipping in the Eastern Conference standings. And Carmelo Anthony is, as you would expect, not happy about it. He's angry. He's confused. And he's also frustrated.

Anthony is apparently so frustrated that, last night, he let his emotions get the best of him. According to the New York Post, a heckler yelled, "Nice defense, Melo," at him in the final minutes of the Knicks' loss to the 76ers at Madison Square Garden last night. And Anthony responded by cursing at the fan.

"Go fuck yourself," he said, according to an eyewitness who spoke to the Post.

That heckler later wrote, "Carmelo told me to F off. Huge Philly fan and I got in his head," on Twitter. But it appears as though that tweet has since been deleted because there's no sign of it on the social media site.

Anthony refused to address the heckling he received from fans after the game. But it's clear that the Knicks have to do something to get back on the right track.

"As a team," he said after the game, "we got to stick together and not let anything come between us."

Haven't we heard this before, though? How much more losing can Knicks fans take?
