With center Yao Ming suffering injuries on a regular basis, the Houston Rockets are always in need of a good backup at the five-spot.

Finally, mission accomplished. The AP reports:

Brad Miller joining Rockets

Free agent center Brad Miller has agreed to a three-year, $15 million contract with the Houston Rockets.

The 7-foot Miller averaged 8.8 points and 4.9 rebounds for Chicago last season. Miller played in Sacramento from 2003-09, including three seasons playing for current Houston coach Rick Adelman.

Agent Mark Bartelstein said in a phone interview on Saturday that reuniting with Adelman was a major factor in Miller’s decision.

“Coach Adelman was a huge part of it,” Bartelstein said. “He had a great time playing for him, and he thinks he’s a great, great coach.”

Miller does not have a lot left in the tank, but as a primary backup center only needed to play limited minutes he’s as good as it gets.
