You know that adage your coach told you about keeping yourself between your man and the basket? The Heat don't do that. Instead, they're fronting everyone and preventing all entry passes.
This is where the Pacers need to do one of two things. One, they could cut backdoor. Someone needs to fight around Miami's fronting to catch the ball, and someone else needs to immediately dive to the basket to get an easy layup.
More fundamentally, though, the Pacers just need to pass more decisively. There are openings to lob the ball over the top, but if the Pacers aren't ready to take advantage of them, they close quickly. Indiana's guards need to trust themselves to put the ball in the right spot instead of playing not to commit a turnover.
