Cavaliers star LeBron James says that he has improved his game over the summer.

James was the NBA's MVP last season, but felt as though there was still room to get better.

"I'm a much better player than (in) our last game against Orlando," he told the News Herald. "I stay in the gym. You guys just see what's on TV. Cameras aren't there when I'm working out."

LeBron did a lot of traveling this summer, but Cavaliers assistant coach Chris Jent and assistant athletic trainer Mike Mancias went everywhere with James.

"He's improved every year I've been here in every aspect of his game," coach Mike Brown said. "Whether it's in the post, catching and shooting, leading the team or handling the ball, he's gotten better. He's one of the hardest workers I've seen. (Former Pacers guard) Reggie Miller is up there in the top three.

"When (James) works, he does things with a purpose."
