The Nets eased to a 103-80 win at Madison Square Garden to condemn the Knicks to their fourth straight defeat in the space of a week.
"That's the only thing that kind of bothers me - today we didn't even fight," Anthony told reporters. "I felt like we didn't fight as a team.
"We couldn't get into defensive sets and [were] just scrambling and double-teaming and switching, basically just scrambling the whole game."
The Knicks were successful with just 34% of their shots from the field in the defeat.
