The Knicks watched film of their embarrassing loss to the Bobcats on Thursday.
"The thing that kept coming back was communication," Carmelo Anthony said. "We weren't talking. We weren't acting, we were reacting.... You could look at guys' faces and see that they're thinking too much. It's just a matter of us just loosening up."
Charlotte shot 55 percent from the floor in the 118-110 win.
"We were awful," Knicks coach Mike D'Antoni said. "A lot of things broke down."
The Knicks rank 26th in field goal percentage defense.
