BOSTON Celtics rookie Marcus Banks helps defeat James and the Cavs

Moved from point guard to shooting guard, James did best in the fourth quarter.
BOSTON (AP) -- LeBron James said the only thing that made him uncomfortable at his Boston summer league debut were the Reebok logos on the backdrop behind the interview podium.
He could have mentioned Boston rookie Marcus Banks, too.
James, the No. 1 draft pick who signed a deal with Nike last month worth about $90 million, had a few highlight reel moments interspersed among a couple of lowlights Monday night as the Cavaliers lost 87-84 to the Celtics before an overflow crowd of at least 2,500 at UMass-Boston.
Two of his worst moments came in the opening minute when Banks drove around him for a layup and James tried to respond. Isolating against the rookie from UNLV along the left baseline, James tossed up a 15-footer that hit nothing but air.
One more airball would follow, but James also had plenty of positive moments while scoring 25 points with nine rebounds, five assists and two blocks.
James graded himself with a C. He won't have a chance to improve that mark until Thursday when he returns from a two-day cross-country trip to attend the ESPY awards.
James played his best in the fourth quarter after the Cavs moved him from point guard to shooting guard, making a pair of dunks before ending the night with a banked-in 3-pointer.
How it went
His best highlight was a flying one-handed dunk after he used a spin move to get around Boston guard J.R. Bremer, who led the Celtics with 28 points.
On defense, he twice blocked shots by Banks. Two other times, however, Banks was able to drive for layups against James despite giving up about 6 inches in height.
"He's quick as lightning," said James, who recalled staying up past midnight to watch Banks' college games on television. "The best thing I could do was to take a step back and try to contest his shot when he went up. I've got a little quickness, but not like him."
Banks finished with 10 points, four assists and four steals, quickly becoming the crowd favorite -- although James won over some of those who paid $15 per ticket.
James' 25 points were his most in three summer league games. He played twice for the Cavs last week in Orlando before leaving the team to attend a wedding.
