DALLAS - Brooding Dallas Mavericks fans looked for reasons why their team failed to win its first NBA title after taking a 2-0 lead over the Miami Heat.

The Heat’s 95-92 victory Tuesday night gave Miami its NBA first championship, a 4-2 win they celebrated on the Mavericks’ court.

“I paid $1,200 for these tickets, and we did not win,” said Ashleigh Adams of Arlington, among dejected fans who streamed out of the American Airlines Center and made plans to drown their sorrows.

“We got the coach. We got the team. We wanted it all this year, though,” said Korby Keene. “The Heat aren’t that good. The refs gave them the game.”

Three people, all Mavericks fans, were arrested on misdemeanor assault charges, and one was treated at the scene after a fight in the arena parking lot. Police said tension from the game contributed to the incident.

Fan criticism of the referees followed the example provided by the Dallas owner.

Mavericks owner Mark Cuban was fined $250,000 on Tuesday for his outbursts following Game 5 of the NBA finals, and commissioner David Stern said he was becoming weary of off-court antics drawing attention from the series.

Cuban was cited for “several acts of misconduct” committed after Dallas lost 101-100 in overtime to the Heat in Miami on Sunday night. The infractions included Cuban going onto the floor to complain directly to official Joe DeRosa, screaming toward Stern and a group of league officials.

Stern was booed loudly by the fans that remained in the stands during the postgame trophy presentation on Tuesday night.

“If we believe that the last great conspiracy theory in Dallas was JFK’s death, the second greatest conspiracy theory was that David Stern wanted the Miami Heat to win the championship,” said fan George Graffy, 41.

“I’m bummed, I’m going to go drink heavily. It will not be a good night,” said James Jones, 50, who sported a suit, tie and a blue mohawk for the game.
