One day the Kings will learn. Or at least it seems they would.

Or perhaps it will take more of what happened in the second quarter Wednesday night at TD Garden to drill home the message.

The Kings became a one-on-one team again. The Boston Celtics, playing without injured All-Star point guard Rajon Rondo, played team basketball.

The result was a 99-81 loss to the Celtics.

"We played a selfish basketball game," guard Isaiah Thomas said. "We didn't do the little things. We didn't take away what they do well; we didn't get stops on defense. We turned it over a little too much, and we weren't in the right spots on the offensive end."

The second quarter was a collection of all the Kings could do wrong.

Sacramento shot 5 for 18 and allowed 13 points off seven turnovers. Boston made its first 14 shots of the quarter and shot 16 for 20.

The Kings led 24-22 after the first quarter but were outscored 37-14 in the second.

Kings coach Keith Smart said he couldn't point to anything the Celtics did to rattle his team.

"I wish I could say it was something Boston did," Smart said.

The second quarter got away from the Kings quickly.

Smart played his starters the entire first quarter to prevent an early 8-0 deficit from becoming a rout.

By the time Smart went back to some of his starters with 6:25 to play in the second quarter, Boston led 41-31.

Smart said the Kings (17-30) were caught dribbling too much, a recurring problem when they struggle.

Before Monday's win at Washington, the Kings had lost four in a row largely because of turnovers and poor decision making and shot selection.
