San Antonio had a five-point lead with 28.1 seconds left in regulation on Tuesday before Miami rallied to force overtime and eventually claim a 103-100 victory.

The Heat haven't won back-to-back games in four weeks.

Miami trailed by 13 points late in the third quarter of Game 6 and the home fans were scurrying to the exits when the Heat were behind by five points in the final half-minute.

But Ray Allen drained the game-tying 3-pointer with 5.2 seconds left and Miami outplayed San Antonio over the second half of overtime to keep alive its hopes of winning back-to-back titles.

"It's so hard. It's the hardest thing," forward LeBron James said Wednesday of repeating as champion. "I said last year was the hardest thing I've ever done – winning my first. Last year (doesn't) even come close to what we've gone through in this postseason and in these finals."
