Having played the NBA’s toughest schedule this far — based on opponents’ winning percentage — the Rockets play seven of their next eight games against teams with losing records. That is not necessarily good news, however. The Rockets have lost their past two games to teams with losing records, in Sacramento and Washington.

“We let two games slip away,” James Harden said. “We’re not allowed to at this point of the season. We have a lot of teams that are under .500 so we have to do a good job of really focusing on trying to win those games.”

Adding a center

The Rockets filled their open roster spot by signing center Tim Ohlbrecht to a three-year deal. As with the contracts given to Patrick Beverley and Greg Smith, the second and third seasons are with team options.

Ohlbrecht averaged 13.4 points, 7.4 rebounds in 32 games with the Rio Grande Valley Vipers. He led the NBA Development League in shooting percentage, making 60.5 percent of his shots, and blocked shots, averaging 1.63 blocks.
