Rajon Rondo Trade

Update- It appears that the Celtics and Rajon Rondo are ready to move on from each other. The Celtics will finally trade Rondo. The Mavericks look like they will land Rondo sooner rather than later. Sooner could be tonight as the deal is done in principle. For a while now the Celtics seemed like they were willing to trade Rondo but now the deal should come together tonight. Of course physicals have to be taken and everything has to be made official.
Here is what Espn had to say.
