HOUSTON -- With the Houston Rockets taking on the Boston Celtics on Monday night, defense has become a main concern.

In the Rockets current three-game losing streak, the team has allowed 107.6 points per game.

"As a team we’re not playing hard enough," forward Trevor Ariza said at Monday's shootaround. "A team is not one individual, its everybody. So we have to get it together. We're slacking and that’s not the type of team we are, that’s not the type of personalities we have as individuals. Whatever the case may be, we have to snap out of it and get it together."

For the season, the Rockets have allowed the third-most points in the NBA at 108.3 points per game and are tied with the third-worst field goal percentage allowed at 47.

"It is what it is," Ariza said. "We're not playing our best basketball right now, that’s obvious. So what are going to do to get out of it? We're going to continue to stay together and just work to get out of it."
