Watch LeBron James long enough and you begin to understand all the intricacies of his nonverbal communications. One of his most animated facial expressions during games is the "Mario Chalmers face."

Similar to James' "Joel Anthony face," the reaction James makes when Chalmers commits an error on the court is unmistakable. James raises his brow, opens his eyes wide and stares with bewildered amazement as if he has just witnessed the most surprising blunder in the history of basketball.

This happened often last season.

This season, though, flashes of James' "Mario Chalmers face" are few and far between. It's not that James is less critical of Chalmers' mistakes — James and Dwyane Wade are more than willing to instruct and direct Chalmers during games — it's that there's not as much to correct. Chalmers is playing the best basketball of his career. Entering Sunday's game against the Hawks, Chalmers is shooting 49.5 percent from the field, 45.2 percent from three-point range and 81 percent from the free-throw line.
