MIAMI — LeBron James is aware of the criticism about his play in the NBA finals. He says his thoughts are on more pressing matters.

Like helping the Miami Heat force the Dallas Mavericks into Game 7.

The Mavericks lead 3-2 in the championship series. For Dallas, it could be comeuppance for 2006, when Miami won Game 6 on the Mavs' home floor. Now the Mavericks are in the same position.

James has managed 11 points so far in the fourth quarters of finals games. Heat forward Udonis Haslem says Game 6 will be "the toughest of our lives."

Meanwhile, the Mavs say they will take a Game 7 approach into Game 6. Coach Rick Carlisle says "there's nobody in our locker room" who is looking at their situation as having two chances to win one game — they want it now.
