Despite the good record and good play without Rondo, I don't think that he is as replaceable as many seem to believe.
Paul Pierce, in particular, has in many ways been able to replace Rondo. Bradley, Lee, or Terry are not the replacement point guard. Paul Pierce is. He is a great player who has taken on the challenge of being a facilitator and a creator in our point guard's absence, as well as a scorer, and he's done a brilliant job of it. We are lucky to have him. I remember being of the opinion when Rondo went down that the only way for this team to stay in contention was for Paul Pierce to step up and be able to consistently lead the team in a point forward role. Up to this point, he's been able to do that.
Hopefully he can keep it up, and he and KG have enough left in the tank to lead us to another improbable run. They won't be able to do it alone. The talented depth that Danny has been able to acquire will need to be big to help them out, particularly Bradley and Green. Everyone else will have to play their roles as well.
This brings me to the point about Rondo's alleged "replacability." Paul Pierce and KG won't be around and playing at a high level for much longer. I like Bradley, Lee, and Green, but none of those guys have that elite ability to create shots either for themselves or for others like a Rajon Rondo or a Paul Pierce do.
I'd love to acquire a promising young big, but none of the names that I've heard suggested as potential trade partners for Rondo are guys that I believe can lead this team to title contention without an elite shot creating guard or wing.
As far as I'm concerned, the smart move on Danny's part will be to continue to be patient, continue to acquire and develop talented young assets to play alongside Rondo as we continue through this rebuilding or "reloading" phase, and then try to flip some for that talented, promising big when some of our assets have matured a little more, or simply find that promising big in the draft or free agency in the meantime.
Panicking and giving away our best young player for limited return based on a small sample of games led by our aging superstars could very well end up being a gigantic mistake for the future of the organization. I don't want to see Danny make that mistake.
