Whether he scores himself or uses others, I don't care. Ultimately, creating points is his job and Rondo is pretty darn good at it.
Most every season, Rondo has averaged somewhere between 37-40 points-created off of shots and assists. Last year, he averaged just under 39. This year, in his 10 games back, he's only created about 26 points per game, but his per-36 rate is 34, which indicates he's climbing back towards where he was. His per-36 rate last year was just over 37.
For comparison, a shoot-first PG like Kyrie Irving currently has a points-created rate right now of 36 per 36. The thing is, Irving is taking between 18-19 shots per 36, at a low FG% of just 43% to maintain that rate.
Rondo last year maintained his higher rate on only about 12 shots per 36, at a tops-among-PG 48.4 FG%. This means, in the course of creating those points, Rondo generated far fewer missed shots.
That's important for an offense to be efficient because missed shots are possession-killers. Over two-thirds of all missed shots go to the defense.
These are the little things that are missed by too many fans.
Of all the PGs mentioned, the only guy who I would take as a clear upgrade over Rondo at point-creation would be Chris Paul - and that's based on his point-creation numbers, only. Paul has been head-and-shoulders above everyone else in point-creation. But Rondo, consistently has been among the top 2 or 3 PGs of all the rest at point-creation (often second only to CP3) and, because of the way he scores, Rondo has tended to do it while generating far fewer misses than most of those other guys.
Rondo obviously has a few other things he's good at as well.
I get that he's not the right cup of tea for some fans. But I, personally, really enjoy the style of basketball Rondo plays. I think he plays smart, team-oriented basketball and I hope he continues to be a Celtic for years to come.
I do wish he'd get better at Free Throws, though. That's the one real weakness in his game, imho. If he could get his FT% up above 70%, that would be just awesomeness.
