Your Boston Celtics currently have the best offense in NBA history. According to Basketball Reference's algorithm, they're scoring 122.2 points per 100 possessions. NBA.com's algorithm has them at 121.5 - either way, an astonishing number.
I think that I'm not alone in ranking Brad Stevens' personnel decisions highly; certainly the addition of a major shot-creator and scorer off the bench in Malcolm Brogdon has made a big difference (true to his word, that fulfilled a need that Brad identified in his post-season press conference).
Then, too, you could point to the development of players, above all of Jayson Tatum.
I'm interested to know what you see about anything having to do with the offense - why is it better? Why is it so much better than last season? It would be interesting to look at the Celtics' offense after the trade deadline last year.
But the main thing I'm interested in here is:
How is Joeball different than Imeball, and how much is it contributing to how good the offense has been? Those are two separate questions.
A few things stand out:
1. Marcus Smart has the ball more. This is especially interesting because his usage% has gone down. He has never had a usage over 20%, but as of today he's at a minuscule 16.6%. His assist% just went up over the golden threshold of 30, the highest of his career. Add to that the stellar Ast/TO ratio, over 3.5, and he's looking a lot like a classic pass-first point guard these days. More than assists, he does a great job of just being a connector, making the next pass.
2. There is more ball movement than last year. But equally or more important, there's more man movement. There are like a LOT more off-ball screens; almost 60 per game compared to about 48 last year. We're seeing a lot of variations on a Strong set, with two staggered screeners on the wing. Out of that, a lot of 45 cuts by one of the screeners into the lane, or if Brown is one of the screeners, taking a pass and driving.
3. Marcus Smart is posting up more. Especially striking is a postup in the lane - meaning that he's making a quick decision, including attacking the basket. In the lane outside the restricted area, Marcus is shooting an excellent .550, but he's more likely to pass to a shooter or a cutter. They're even running a pick and roll with Smart as the screener and Tatum as ballhandler to get them both a mismatch.
4. Jaylen Brown is getting to the rim more. Fewer threes and fewer lane shots outside the restricted area. His more efficient midrange game is a powerful weapon, since most defenses aren't geared toward defending it. But he isn't shooting it more, just better. Same thing with his FT shooting; his FTr is good but not elite at .261 - about the same as last year; but he's shooting a career-high from the line: .832, which is A-plus. That's a huge achievement, looking at his career; it's just because of patient, steady work.
5. The Two Jays® have usage rates comparable to last season, with assist rates slightly lower.
What else?
