Per Jonathan Feigen: The Rockets are still hoping to add a backup center and have made an offer to Bulls free agent Brad Miller. Miller’s agent Mark Bartelstein said Wednesday that nothing had changed, with Miller continuing to consider his options including the Rockets. "We really have an unknown with Yao (Ming)," Adelman said. "We didn’t know how he’s going to come along. The one area we have a big hole is, what are we going to do at the center spot. It’s still a real, real question mark. We looked at all the big guys out there. We don’t want to go through the season again having to play Chuck (Hayes) or that small again there (at center). I think it wore us down." Props to olivarezq1 for the find.
