The Spurs turned a 14-point halftime lead into an 88-75 deficit entering the fourth quarter against the Heat on Tuesday night.

“I thought in the second half they got real physical, and I thought we folded,” Popovich said. “The physicality killed us. We had nobody that stepped up. We let the physicality beat us in a lot of different ways — whether it was cuts, or passing or boards. It didn’t matter what it was. Their physicality put us in a ditch."

The Heat outscored the Spurs 71-35 after intermission.

“They beat our ass in the second half," Popovich said. "We should be embarrassed by that, playing that soft.”
