I don't think we have enough to get Battier with guys that we would be willing to give up. They would be looking for an expiring + a good draft pick (~13-16 range) or a good young player - maybe a Gortat for Battier type deal could be worked out later this year. I think Battier will be available, but Houston wont give him away for nothing. The only chance we could have had is resigning Baby and then trading him later in the year, but Houston is stacked at the pf spot with Scola/Landry/Hayes/Dorsey.
You have to factor in two concerns on Houston's side.
1. Given Yao's injury history, how confident are they in building around him?
2. Given McGrady's playoff history and expected salary demands when his deal expires after the coming season, will the Rockets push hard to resign him?
Both of those questions may nudge Houston into "blow it up and rebuild" mode, where offloading Battier for expiring deals is the logical choice. Now, I wouldn't necessarily want Ainge to give up a 1st in a deal for Battier, and that might be something the Rockets demand.
