The Houston Rockets are interested in trading for Rajon Rondo.

The Boston Celtics have been shopping Rondo ahead of the deadline, though they will likely need a huge return in order to pull the trigger.

Darryl Morey and Danny Ainge are former colleagues in the Celtics' front office.

The Celtics would insist upon Chandler Parsons in a deal for Rondo, which appears to be a dealbreaker at this point for the Rockets.
