I'd like to point out that we have much more cap space with Rondo than we do with Chris Paul to improve the team in the summer of 2012. It would be at least a $7 million difference depending on what Chris Paul's next deal is valued at. That's a pretty significant number, especially when we consider the unknown parameters of the upcoming new salary cap structure.
We have a $10 million expiring contract in Ray Allen, and a $20 million one in Kevin Garnett. If Danny can find the right deal for young, athletic, talented players to go forward with Rondo, I wouldn't be averse to moving one of those guys.
The beauty is that he's in the driver's seat. If the right deal doesn't come along, he can wait until next off-season where he has plenty of money to shop for free agents and some nice draft picks along with still having Rondo and Pierce. At that point, if Kevin and Ray can still play, he might even be able to sign them to last gasp cheap contracts.
There are lots of options out there, and I don't subscribe to the all eggs in one basket approach.
Keeping Rondo, who I don't think is close to reaching his peak as a player, makes the most sense to me.
