When the Heat walked off the floor following their Game 5 loss to the Celtics, a young boy repeated shouted "Good job! Good effort!", which was picked up by ESPN's microphones.

The video went viral via YouTube and Twitter in the hours to follow.

The Miami Herald found the boy, a nine-year-old from Coral Gables named Jack Meyer.

"For those people who thought I was being sarcastic, you're wrong," Meyer said on Wednesday. "I was being enthusiastic. I was saying the truth. I would never hurt the Heat's feelings like that."

The loss put Miami on the verge of elimination.

"Based on their expressions, they didn't seem happy being beaten by four points. I wanted to cheer them up," he said. "I really meant it."

Meyer appears to be an eternal Heat optimist.

"The Miami Heat are real winners. It doesn't matter if they win or lose. In my heart they win every single game," Meyer said. "In my heart, every year they get the championship."
