Any Boozer to the Rockets rumors I have seen are mostly fan created
I would be surprised the Rockets had any interest because he doesn't appear to fit any of the things they have reportedly been interested in from an Asik deal which would be one or more of the following. Backup center, stretch 4, draft picks, and expiring contracts.
I just don't see them having an interest in a Boozer who, for them, would be a highly overpaid backup PF who is well into the back end of his career.
