Miami Heat coach Erik Spoelstra is right: Story lines change quickly in the NBA playoffs.

After nearly 48 hours of questions about the Heat's lack of everything — offense, defense, size — against the Indiana Pacers, they unleashed an offensive fury against the league's best defensive team.

Miami put together its most complete effort of the Eastern Conference finals and pounded the Pacers 113-94 in Game 3 on Sunday.

The Heat's five starters scored in double-figures, led by forward LeBron James' 22. But the biggest performance — and maybe most surprising — came from forward Udonis Haslem, who scored a season-high 17 points on 8-for-9 shooting.

The Heat shot 54.5% from the field, held the Pacers to 39.7% and now lead the best-of-seven series 2-1, and Game 4 is Tuesday (8:30 p.m. ET, TNT).

The consternation over Miami's future after Game 2 was necessary. It had not played its best against the Pacers in the first two games — some of that Indiana's doing, some of it Miami's mistakes.

But the Heat delivered a powerful reminder they are the defending champions.

Miami had the league's best road record this season, are now 5-0 on the road in the playoffs this season and have not lost two consecutive games since early January.

The Heat, like that, regained the home-court advantage they lost in Game 2.
