IF YOU THOUGHT the Spurs’ blowout win in Game 3 was a fluke, think again.

San Antonio moved to within touching distance of their fifth NBA Championship with another power punch that left the Miami Heat reeling — and the fans heading for the door.

The Heat need a miracle — no team has ever come back from 3-1 down to win the NBA Finals — but the Spurs aren’t getting complacent.

“They’re the two-time champs, they’re a great team and there is still one more game,” Tony Parker said.
