Should Heat's buzzer-beater have counted?

DALLAS – It appeared that the officials missed a backcourt violation against the Heat on the final play of the first quarter, which resulted in the points that made the difference in Game 3.

Mario Chalmers did not have his right foot established in the front court when he caught a backwards pass from Udonis Haslem. Chalmers took one step and launched a 36-footer, making the shot to give the Heat a seven-point lead in the 88-86 win over the Mavericks.

“They throw in a halfcourt shot that may have been a backcourt violation at the end of the first,” Mavs coach Rick Carlisle said, lightly questioning the call without prompting. “That’s a great play for them, and it’s a tough one for us.”

The call is not reviewable, according to NBA spokesman Tim Frank.
