In the modern NBA, you'll sometimes see games in which both teams run zone defense. This almost never used to happen, but zones are becoming more popular. This is a game that featured both teams use both zone and man to man defenses at times. The Heat's offense was unstoppable, executing well and playing with great force and effort. The Sixers could score a decent amount against the Heat's zone, but they were clearly confused at how to execute effectively against it well enough to beat a hot team. Twitter: @drawing_defense
