Once Celtics GM Danny Ainge came to the conclusion that Boston’s aging core was no longer capable of contending for a title he traded away Paul Pierce and Kevin Garnett and plunged the team into a full-fledged rebuild in the process.

But a rebuild has to begin with elite-level talent at some point and Rondo is a piece that the team apparently had no intention of trading at this time.
