Ben Simmons and Joel Embiid certainly aren’t acting like playoff first-timers, and JJ Redick provided the veteran leadership that the 76ers so desperately needed.

Simmons was the first rookie to since Magic Johnson in 1980 to have a playoff triple-double, Redick led the 76ers with 24 points and they moved one win from the second round by topping the host Heat 106-102 on Saturday to take a 3-1 lead in their Eastern Conference first-round series.

“I’m shocked that we won this game,” 76ers coach Brett Brown said. “We really didn’t have a right to win the game.”

Here’s why he said that: His team turned the ball over 27 times, shot 7 for 31 from 3-point range and trailed by 12 late in the third quarter in an extremely hostile environment against a desperate opponent.
