He was wide awake. Every time he tried to close his eyes, the errors and mistakes would replay in his head. It was 5 a.m. on Wednesday and rather than sleeping off the Miami HEAT’s Game 3 loss to the San Antonio Spurs, Mario Chalmers was up watching film, trying to pinpoint what he’s been doing wrong.

“I am a little bit [of a perfectionist],” Chalmers told Basketball Insiders. “I dwell on things too long and I just need to let them go.”

Chalmers is struggling mightily right now, averaging just 3.3 points, three assists, four fouls and three turnovers through the first three games of the 2014 NBA Finals. He’s shooting just 25 percent from the field and 20 percent from three-point range. In the last 30 years, Chalmers is the only Finals starter who has totaled 10 or fewer points and shot 25 percent or worse from the field after playing 50 or more minutes, according to ESPN Stats and Info.

While his disappearance in the Finals has led to widespread criticism, his poor play actually started earlier in the postseason. Chalmers has now scored in single-digits in 12 consecutive games, and his highest scoring game of the playoffs was a mediocre 12-point outing in Game 1 of the Eastern Conference Semifinals against the Brooklyn Nets.

Chalmers doesn’t seem like himself, on or off the court. The 28-year-old point guard, who has made a name for himself with his swagger and clutch plays, is lacking confidence and questioning himself. After Game 3, a dejected Chalmers stood in front of his locker, shaking his head and taking the blame for the loss.
