His shooting fell off a cliff last year already. If you draw the line to the LA/Minny trade date (2/9/23). Up until that day he was 42.3% from 3, and after that he shot 30.9%. That is a huge 11.4% difference. However, he did still put up the points and actually had 28.7 PPG average after the deadline. Now there is some correlation between those two things (the trade and his shot falling off) but not to that degree. It was mostly just hitting a skid for him. But it also means he was creating a lot more points in other ways than just slingshooting triples.
Here is a related comp:
4.1 made threes per game in December where he shot blazingly hot (48.6%) and averaged 26.8 points (45.9% of his PPG came from 3 pointers)
3.1 made threes per game in March, where he averaged 28.5 points (32.6% of his PPG came from 3 pointers).
If you look at his season (66 games total) as a tale of two halves:
First 33 games (2nd option scorer with better supporting cast)
33.9 MPG, 23.1 PPG, 8.2 RPG with 53/43/84 splits
Last 33 games (1st option scorer with weaker supporting cast in about half of the games)
35.0 MPG, 28.3 PPG, 9.1 RPG with 47/36/89 splits
What is the most interesting thing here is we actually didn't see much of him as the #1 option with a solid supporting cast. January is the best indication of how that could have turned out as he was already elevated to the #1 status by the team at that point and still had Conley, Vando, Beasley and mostly healthy team around him. And he did manage to put up 28.5 points with 49/44/89 splits in January.
