well, they did play them fairly close deep into the third, then they completely and utterly ran out of gas against a high-intensity Heat defense. nevermind that some of that early stuff was a bit of a mirage (Green's shooting, Leonard's orebs). the Heat absolutely have it in their hands to make the Spurs' offense look bad and unless you get huge games from Parker and Duncan plus solid support from their roleplayers, they'll struggle mightily. the defense is looking mostly good, though, so that's something.
