The Heat struggled in the first half of Game 1 defensively, and their rotations were just torn apart by Pacers movement. Here's one example. Watch what happens here when the Heat go to trap Paul George in the post, and LeBron James gets caught trying to keep a body on David West and help on Hibbert.
Notice the way LeBron turned his head at James after the Hibbert score.
Hibbert finished just 3-of-9 in the first half, but that opened up things for David West (4-of-5) first half for eight points. Indiana's killing the Heat with ball movement and finishing power. Can they sustain it or will the Heat figure out how to counter?
