The Cavaliers have one collective goal: winning an NBA championship. James said anything short of a title will be a disappointment.

"We came close," James said. "I got a little taste of it when we won the Eastern Conference championship (in 2007). I need more and the fans need more. They deserve it."

The addition of guard Mo Williams has sent a lightning bolt through the fan base and the organization. Finally, many think James has his sidekick.

"I guarantee if you talk to everyone today, their goal is to win a championship," Williams said. "Every team in the league is saying on media day that they are going to win a championship."

James said the 2008-09 Cavs are the best team on which he's played. He likes the team's depth and talent. He said he's come back this year a better player. Remember, he was a first-team All-NBA choice last year and led the league in scoring at 30 points per game.

James helped Team USA win a gold medal in the Beijing Olympics. He said he stores his medal at his office.

He said facing the likes of Kobe Bryant, Dwyane Wade and Carmelo Anthony every day in practice took his game to a new level.

"There's no way you can't get better," he said. "If you can go out and lead guys who are already established, guys who won NBA championships, scoring titles, MVPs and Rookies of the Year, then I should be able to lead Daniel Gibson."
