The Knicks were beaten up badly on the glass early in the game vs. the Pacers. The Pacers turned the ball over seven times, but other than that, they're getting what they want offensively. And they are crashing the glass aggressively. The Pacers had seven offensive rebounds while the Knicks had 11 total rebounds.
And New York is getting frustrated with it. Watch the Knicks' body language on this Roy Hibbert putback.
