Because there is no shortage of strong voices in the Miami Heat's locker room with LeBron James, Dwyane Wade and Chris Bosh in leadership roles, Udonis Haslem picks his spots when he wants to be heard. He had something to say Sunday. With home-court advantage being stolen away by the Indiana Pacers in Game 2, and much of James' supporting cast struggling, Haslem knew it was time to break his relative silence. “Obviously, we've got so many guys who have won and have been successful throughout their careers at this level, so on different nights different guys speak up,” said Haslem, the only player other than Wade who has been with the Heat the past 10 years. “This time, it was me. Just coming into this game, I wanted to make sure that we came in here with a certain attitude. Something had to change.” Haslem wouldn't reveal all the details of his message to the team before Game 3 on Sunday. But the theme was Miami needed to play like it was an elimination game and its collective Big 3 experiment -- and legacy -- were at stake. Apparently, the Heat psyched themselves into believing it. Storming to a 70-point first half, the Heat built a double-digit lead and cruised to a 114-96 rout to hand the Pacers their first home loss of the playoffs. In the process, the Heat reclaimed home-court advantage and take a 2-1 series lead into Game 4 on Tuesday at Bankers Life Fieldhouse. The Heat shot 54.5 percent from the field, including 42.9 from 3-point range and had 21 assists with five turnovers. After dominating the offense in the first two games of the series, James benefited from plenty of support with all five Heat starters scoring in double figures. Much of the production during the highest scoring first half in Heat playoff history came from some unlikely sources. It started with Haslem, who made six of his first seven shots and scored 13 of his 17 points in the first half. Before Sunday, he made just one shot in the previous two games.
