The Dallas Mavericks walked off the court last night down 3 - 0 in their best-of-seven series with the Denver Nuggets. Forward Josh Howard and owner Mark Cuban were absolutely livid with officials for failing to call a foul on Antoine Wright who was trying to foul Denver forward Carmello Anthony just before he hit a game-winning 3 pointer. The NBA's president of league and basketball operations said in a statement issued by the league about two hours after the game, At the end of the Dallas-Denver game this evening, the officials missed an intentional foul committed by Antoine Wright on Carmelo Anthony, just prior to Anthonys three-point basket." The admission from league officials comes offers little comfort to the Mavs as they try to become the first team in league history to come back from a 3 - 0 deficit to win a playoff series.
