Chris Paul has always been the guy I'd want to replace Rondo. Of course I would strongly consider Derron Williams and Derrick Rose, but Chris Paul just fits the mold.
I can't, however, say I'd definitely pull the trigger on a deal if it doesn't help the team now and later. I'm not sure if Rondo + Green for Paul + Okafor helps us all that much. We'd get an undersized and oft-injured center and lose a very good bench player who can actually play 3 positions.
If we can find a way to get Paul for something like Rondo, BBD S&T (wishful thinking), a pick (not the Clippers') and maybe another filler, I'd definitely do it.
Although CP3 may not be as great a passer as Rondo or as great defensively, he will change the offense immensely. I think without question they become the best offensive team in the league, even better than we looked with Shaq last year.
There's no guarantee Howard is coming here. Calling it a longshot would be an optimistic view. But we would be in better position with Paul than we would with Rondo, assuming we are enough under the cap in both scenarios. Taking on Okafor would make it that much more difficult, but not impossible (DA could move something like Okafor and Bradley for an expiring contract if such a one exists next season).
I guess I would do it. So long as we can get a good F with the MLE, another vet big (Murphy?), and resign Wafer and Delonte. The MLE would need to backup both Pierce and KG, which is hard to do. Maybe 'Quis for the vet min if he is cleared and then a legit PF?
It would kind of be Rondo and Perk for Paul and Okafor, which is a pretty fair deal IMO. I'd still try to get Rondo for Paul without taking on Okafor (Ariza maybe). Rondo is a legitimate All-Star signed at a cap-friendly deal. Paul is better, but not significantly. Sweeten the pot with picks or whatever, and maybe NOH takes it.
