Speaking to reporters after the Sixers took a 3-1 series lead, Brown said he was surprised they won.
"I'm shocked we won this game," Brown said, via Josh Friedman of 790 The Ticket. "We didn't deserve to win this game."
It was an ugly game for the 76ers, who committed 26 turnovers and shot 7-of-31 from three-point range. Joel Embiid, who scored 23 points in Game 3, finished just 2-of-11 from the field. But the Heat turned the ball over 19 times, shot 13-of-25 from the free-throw line and were out-rebounded 57-43.
Per ESPN Stats & Info, Philadelphia's 17 first-half turnovers marked its most in a game this season. And Miami appeared to be in control with an 83-73 advantage with 79 seconds left in the third quarter.
The 76ers, however, went on a 14-0 run and never relinquished that lead. They are within one victory of the franchise's first playoff series win since the 2011-12 season.
Brown had every reason to be stunned by the result, but Philadelphia is riding an incredible wave with 19 wins in its last 20 games.
