The Knicks have lost nine games in a row, while the seven successive defeats at home is a new franchise record.
"I think we're playing to lose rather than playing to win right now," the 29-year-old told reporters.
"When you lose games the way we've been losing them at home, on the road, you start thinking a lot.
"You start playing a little tense. You start playing on your heels."
The Knicks face rivals Brooklyn Nets in their next game on Thursday night.
