In GM 1 they played swarm D for 36 min then fatigue set in the 4th. In GM 3, they mailed in the game for whatever reason. In Gm 2/4, they reverted back to the swarm D & never let their feet off the pedal.

OKC showed the blueprint to beating the Spurs is to disrupt their ball mvt......and Miami has the personnel to do so, thus it's a matter of them putting in the work for 48 minutes & not letting their feet off the pedal for a full 48 minutes. IMO, if the series goes the full 7 adv. Spurs b/c Miami's D is fully dependent on their energy level....I'm not sure how well their legs will hold up playing back-to-back Gm 7 series.
