Rondo's clearly a better rebounder, though more on the defensive end I would guess.
Actually, Rondo is the slightly better rebounder, and its offensive boards that set him above CP3, not defensive boards. Chris Paul is actually a better defensive rebounder over their careers, and ROndo the much better offensive rebounder, by the metrics.
But in terms of overall rebounds grabbed against possible rebound opportunities, their difference is very slim; 7.2 Rebound Rate for Rondo to 6.9 Rebound Rate for Paul.
I'd say Rondo is better at getting to the rim, and that IMO he does a better job at directing traffic/creating mismatches in the halfcourt than pretty much any other pg I see.
Well, simply put, I disagree I guess. I think all things being equal, CP3 having the same weapons Rondo has had, same turnovers created that he can capitalize on, same fast-break opportunities, I think he'd show that on offense he's above rondo in all the categories you mentioned.
Defensively, I'm in the minority when I say I think that they're a lot closer than others might think. I think that KG and Perk, and to a lesser extent Jermaine O'Neal and Sheed, has inflated Rajon Rondo's defensive reputation a bit, to the point where stops that are actually the work of the great rotation in the post get attributed to Rondo on the stat sheet.
Okafor and West are both pretty good defenders, aren't they?
David West is not a good defender. Emeka Okafor I'd put on par with Perkins. Better help defender, worse man on man post defender.
But as you go down the line, the defenders get worse and worse. Carl Landry, Aaron Gray, Jason Smith, just a rotating carousel of terrible defenders.
