Game 4 will be tight, both teams are likely to make a lot of mistakes. Fourth quarter execution will be key. Defensively, the Spurs found a gem tonight. Pop clearly adjusted to have his players stay at home on shooters and not bring help D until the last possible second, and it paid off beautifully. Spoelstra will definitely adjust, and the Heat will bounce back. The Spurs need to anticipate that and understand that they will not shoot 16-32 from 3 again. Parker has to get the offense running the way it's designed to run. Losing Game 4 will not ruin much, but it would put immense pressure on the Spurs to take Game 5 going away. The Heat will only get more dangerous when the series shifts back to South Beach.
