Sacramento Kings coach Mike Brown used a laptop to help demonstrate what he feels are calls to have gone against his team from the NBA officials.

Brown was ejected after he stormed onto the court to confront referee Intae Hwang during the fourth quarter of the Kings' 143-142 overtime loss to the Milwaukee Bucks on Sunday.

The Kings have lost three of their last five games, but coach Brown was not willing to let his team take full accountability for the loss to the Bucks.

Instead, during his postgame news conference, Brown wheeled out the technology to show what he believes were inconsistent calls from the referee.

"The referees are human, and they're going to make mistakes, but you just hope that there's some sort of consistency and there's some sort of communication between the refs," Brown said.

"The refs tonight, they were great, they communicated with me all night. But in terms of consistency, you guys saw it right here. In my opinion, the consistency wasn't here tonight.

"We had a chance to win the game and we didn't get it done," Brown said. "But I'm telling you, man, to go through [the inconsistency in calls], it's tough, man. It's tough to go through that."

Despite Brown's ejection, the Kings came back from 12 points behind to force overtime, in which they went ahead, only to be condemned to a defeat by Damian Lillard's long 3-pointer just before the buzzer.

Bucks coach Adrian Griffin said: "It was like we had the game and they stole it from us and we took it back at the end.

"When they went up six, it would have been easy for us to throw in the towel, but those guys are resilient. Probably one of our best wins of the season."

The Bucks look to be back on form after a slump earlier in January, and have now won their last three games. They sit second in the Eastern Conference, with the Kings sixth in the West.
