Just a note on rebounding as well. Rondo has huge hands and great instincts which allows him to get a lot of rebounds for a PG... but it's partially because of weaknesses as well.
Our bigs aren't very good rebounders. Part of the reason they aren't very good rebounders is because of our defensive schemes that often have our bigs out of the paint when a shot goes up. On offense, our bigs are usually operating in the mid-range where they are effective hitting mid-range shots. Part of the reason they are operating in the mid-range, is because Rondo needs room to penetrate and kick out. Part of the reason he needs room to penetrate and kick out is because he's a horrible shooter and teams can (and do) slack off him 5 feet when he has the ball. We need bigs to spread the floor, because of Rondo's weaknesses. When bigs are used to spread the floor, that means your bigs aren't always in proper rebounding position. That allows Rondo to snag several rebounds.
If Rondo was a capable shooter, he would command coverage from defenders. If Rondo was a great shooter (like a Nash or Chris Paul), he'd command double coverage from defenders. That would allow us to have a traditional post playing big man (like an Al Jefferson) who could hang around the paint, grab rebounds and post up players while Rondo commanded attention outside the paint. And I'm not saying Rondo wouldn't still be an above average rebounder for a point guard... but it's safe to say he would average a heck of a lot less rebounds if he could shoot. Our team is partially constructed around his strengths and weaknesses. There is a reason why Doc specifically wanted Glen Davis to focus on his mid range shooting... There's a reason Ainge specifically went after a player like Brandon Bass (known for his consistent mid-range shooting)... it's because it allows Rondo to be his most effective. We're putting a premium on bigs who can shoot outside as opposed to bigs who can bang inside, clog the middle and pull down rebounds.
That said, when Shaq was here our offense flourished... so I'm basically just talking out of my butt.
