Dallas ended Game 2 on a 22-5 run, which said plenty about their mental toughness and a little about Miami as well. The Heat was done in by a lethal combination of premature celebrating and inexplicably settling for long jump shots.

"Every team when they go on a run does something," Dwyane Wade said. "Celebration is confetti and champagne bottles. There wasn't a celebration. If it pumped them up ... they won the game."

The Mavs appeared to be done when Wade completed an emphatic 13-0 run with a 3-pointer. He and the Heat celebrated like the game was over, a moment that was not lost on the Mavs.

"It was the turning point of the game," said Jason Terry, who scored eight of his 16 points in the fourth. "If we don't score, we're pretty much dead."

After the Heat took an 88-73 lead with 7:15 left to play, Miami missed 10 of its last 11 shots. Seven of those shots were 3-pointers, including Wade's runner from behind the arc that hit the back rim as time expired.
