The Cavaliers' first scrimmage is Saturday night in James' hometown of Akron, while the first preseason game is next Tuesday.

"It's a dream come true," James said of playing with O'Neal. "You always want to play with a great. It's awesome to be out on the same court with him. He's in really good shape, honestly. It's still early."

This is James' first time sharing the spotlight, while O'Neal had a turbulent relationship with Kobe Bryant in Los Angeles before moving onto Miami and Dwyane Wade. He won championships in both cities, though Bryant and O'Neal often clashed over the spotlight.

At the team's media day on Monday, O'Neal, who has said he and Bryant are no longer at odds, conceded that he is older now and not as concerned with headlines.

James said Wednesday he isn't worried about who will be the focal point of the offense.

"I can make adjustments no matter what goes on," James said. "Me and Shaq will be features of the offense with Mo, also. I can play off Shaq, he can play off me, so it doesn't matter."
