Thunder coach Scott Brooks called his team soft after Oklahoma City's 35-point home loss to Portland on Friday. After Sunday’s 117-99 loss to Indiana, Brooks said he was stunned his team didn’t play with better effort. On Monday, Brooks said he takes his team’s recent lack of effort personally. “I definitely take it personal. It hangs over me,” Brooks said. “We have to bring enthusiasm. We have to bring energy. Every game, I want guys to play with effort and my job is to find that effort. If a guy doesn’t have it I have to find somebody that can bring it and spark us by bringing that energy.” The Thunder enters Tuesday's game against San Antonio having lost five straight at home, losing by an average margin of 17 points over that span. “I want to figure out ways that we can get better,” Brooks said. “Whether we win or lose, I’ll still challenge myself to get better and figure out ways to make us look more complete.” Rotation to stay the same Despite the recent lackluster performances, Brooks said he hasn’t considered tweaking the starting lineup or making any changes to his nine-man rotation. “I’m hoping that it’s a two-game streak and doesn’t turn into three,” Brooks said. Defensive consistency the biggest issue The Thunder has not shot well the past two games, but defense has been the biggest issue. “The first part of defense is out front stopping the ball,” said Brooks. “We can’t allow the ball to continue to get inside the teeth of the defense. It’s done that the past two games. We’re not a team that’s built to outscore teams in the 100s. We have to focus on defense. We have to be able to score off our defense. That’s when we’re fun to coach.” White aiming to rebound better After scoring 14 points on 7-for-8 shooting in his NBA debut Sunday, rookie forward D.J. White said he was pleased with his performance but needs to improve his defense and rebounding. He finished with only two rebounds Sunday. “That’s one thing that I hang my hat on, rebounding,” White said. “I just got to be more aggressive going after them. That’s the main thing.” Spurs killers In one of those hard to explain occurrences, the Thunder has played the Spurs as tough as any team on the schedule this season. The Thunder’s last home win came against San Antonio on March 16, when the Thunder erased a 17-point deficit to win 78-76. Last Tuesday, Oklahoma City owned a double-digit lead much of the second half and held on for a 96-95 win. “We’ve played pretty well against them,” said Thabo Sefolosha. “We know they’re going to be ready.” The Spurs will be without guard Manu Ginobili , their third leading scorer, Tuesday because of an ankle injury.
