Option 2: Andris Biedrins, a 2013 second round pick and a 2014 second round pick to Boston Celtics for Brandon Bass
The Celtics could use a backup center and Biedrins could possibly fill that role. He would be an expensive option for your backup center, but if Boston is looking to get younger two second-round picks would help.
The Celtics are eventually going to have to trade or get rid of Brandon Bass or Terry, and if Landry leaves than Bass would be a perfect replacement.
Boston would rather sign a cheap backup center like Nazr Mohammed or Jason Collins Both are much cheaper to bring in than Biedrins.
Likelihood of happening: 3
