The Knicks lost their sixth straight game on Monday, leaving them bottom in the Atlantic Division.
The head coach told ESPN: "I don't think I have lost the locker room. I don't think I have lost players from an individual standpoint. What I have lost is a Tyson Chandler and a Raymond Felton [to injury], that is what I have lost from my starting team.
"And I don't know if you can go on any roster and take two starters out of their roster and they still survive. They might play in spurts like we are doing today. I am not making excuses, but I would sure love to take my chances with Tyson and Raymond in my lineup.
"There are a number of things that you can point the finger at. I always look at the defensive end first because that is where it starts. I will address that. It is a reflection on all of us. Me being the coach and guys that go out there and play, it all goes hand in hand."
The Knicks travel to the Los Angeles Clippers tonight.
