MIAMI --- LeBron James came to Miami last summer for the chance to be a champion.
He arrived Friday just hoping to be a survivor.
The Dallas Mavericks have a 3-2 lead in the NBA Finals and can win their first championship Sunday night.
Less than a year after the Heat's free agent victory celebration, the real party might belong to Dirk Nowitzki.
But the Heat insist they can still win the first of multiple titles James boasted of upon his arrival in South Florida.
"I guess they have momentum in the sense they came home and won two games. But each game is its own," Dwyane Wade said Thursday night. "We're going to come out -- every game has been pretty much a possession here, a possession there. Either team can come in and say they can be up different than what they are. We'll be coming to the game understanding it's a possession game in Game 6, doing whatever it takes to win the ballgame. So we're confident."
So are the Mavericks, who get two chances to close out the Heat, but stress the importance of doing it on the first try.
"Game 6 is Game 7 for us," guard Jason Terry said. "We want to play like there's no tomorrow. If we do that, I have no doubt in my mind we can be successful. We must come out aggressively."
Wrapping it up on Miami's floor would be the sweetest revenge for Nowitzki and Terry, who launched the Mavs' final shot that Wade rebounded and fired in the air as the clock expired on Miami's Game 6 victory in Dallas in the 2006 finals.
A Heat victory Sunday would set up a Game 7 on Tuesday night.
