BOSTON -- Cleveland Cavaliers coach Paul Silas just shook his head after watching LeBron James torch the Boston Celtics for 25 points, nine rebounds, five assists, two blocks and just two turnovers here at the Reebok Pro Summer League on Monday.

"He's getting better," Silas said smiling. "He finds a way to get it done. I thought he took another big step tonight."

Guarded primarily by Mountain West defensive player of the year Marcus Banks and third-year swingman Kedrick Brown, LeBron overcame a rocky start to lead the Cavs in points, rebounds and assists.

Banks challenged James on the opening possession, taking the ball right by James for an easy layup. James responded with a cross over move to get space from Banks, but ended up shooting an airball. James ended the first quarter with just two points on 1-for-4 shooting. But after that, he took over, posting up the smaller Banks and taking the bigger Brown off the dribble.

"He's got such great poise," Silas said. "I think the best way to define him is by how he accepts challenges. He calmed himself down and really picked up his game."

James was at his best, offensively, when Silas moved him off the point and had rookie point guard Kristaps Valters running the offense. The move allowed James to come off screens and get more open looks at the basket. James was especially effective posting up his man down low. Twice he spun baseline and beat his man to the hoop -- once for thunderous dunk that evoked cheers from the crowd.

While James clearly looks more comfortable at this point playing small forward, Silas says he's going to keep him at the point.

"His teammates already love him because he gives up the ball," Silas said. "He's not a selfish player at all. They're going to love playing with him."

Teammate Carlos Boozer already does.

"He creates for us," Boozer said." He makes very good decisions. He's aggressive, plays hard -- I'm impressed. He creates a lot of things for his teammate because he drives to the basket and draws defenses. That leaves us open for dunks and layups."

Boozer face was on the receiving end of several of those "creative" passes. Two times in the second half a no-look pass from James bounced off Boozer's head. One time the ball landed right back into James' hands for an easy lay-up.

Both Silas and Boozer aren't afraid to heap big expectations on LeBron's shoulders.

When asked what he expected of the Cavs, who finished with the worst record in the NBA last year, Boozer was quick to come up with an answer.

"Playoffs. We should set that goal now and do everything we can to reach it. We just need to come together. We're already doing it."

Silas too seemed comfortable predicting James's future just three games into the NBA summer league.

"He has the capacity to be a super player. It's going to take time. But all the ingredients are there. The only question left is can he win and can he win big."

Leave it to LeBron to be the one to try to calm down the rampant expectations. James pointed out several times in the news conference that his team lost. Winning is how he wants to be gauged which is why he gave himself a "C" for the night.

"You only get an "A" when you get a victory," he said.

"Don't judge us too quick, we still have veterans to add," James said. "We're going to be a whole different team when the season starts. This is the summer league."

Still LeBron seemed pleased with how his first few weeks in the NBA have gone. He says he's enjoying himself, looking forward to a vacation after the summer league and generally thinks that it's better not to think about what's coming next.

"Everything is going fine, it's running smoothly so I'm going to try to not think about it," James said. "Don't fix what isn't broken."

Somewhere, Paul Silas is giving an amen.
