You may be relying too much on the numbers. The eye test revealed to many of us that that his style from the previous season, was a better fit for this team. It's not about refusing to shoot the 3, as much as it is not settling for it as much. His best skill that will translate to the playoffs is applying pressure on the defense, by getting into the lane and mid/short range where his shot is elite
Two things can be true here:
(1) As fans we're unhappy to see Fox settling for threes because over the course of his career we've seen him excel as a slasher and mid-range shooter and the increased volume of threes he took this past season negatively impacted his overall shooting efficiency.
(2) The team is ultimately
better with a version of De'Aaron Fox who is as capable as an outside shooter as he historically has been as a slasher and transitioning his offensive game away from pure athleticism and finishing ability toward a more perimeter based skillset will allow him to stay relevant in the league longer.
Is it not possible that what was good for Fox was not good for the team as a whole this season? Clearly the offense changed and him taking more 3s, not always good ones, was a part of it. Especially at key moments of the game, I recall him taking a few in clutch time that missed where last year he would have taken them to the rim.
Also what about (theoretically) getting opponents into foul trouble early?
I am not mad that he developed the 3 and hope he keeps using it as a tool but we all saw what we saw. And I think it's also just part of a frustration many of us have with the modern game. Analytically it makes more sense to shoot 40% from 3 than it does to shoot 55% from 2, but typically you don't draw fouls and passing can be less effective when it's around the perimeter than the drive and kick, which I guess is how I am understanding the "spray" to be even though I felt our offense often lacked that.
I would agree with most of what you expressed here. I also prefer to see players driving the ball into the defense and forcing the other team to make a play to stop you. But the mitigating factor here is that even if Fox is fouled that gets us nothing unless the officials call it a foul and they've been reluctant to do that. And complaining about it only gets you less calls. So the choice isn't necessarily up to us about which style of play we prefer so much as it is about adapting to how the league wants to see the game played instead of stubbornly hoping something will change on the officiating end.
Let's look at the overall 3pt shooting though. Has it really changed that much from 2023 to 2024? According to team stats, the Kings as a team attempted 37.3 3pt shots in the 2022-2023 season and 39.3 3pt shots in the 2023-2024 season. Those shots weren't coming from Fox as often in the previous season (5 per game instead of 7.8 per game) but with Monk, Murray, and Huerter all shooting around 35-36% on their attempts in 2023-2024, it made sense for them to shoot less and Fox to shoot more. The more significant change was seen in the fourth quarter shot distribution. Whereas a year ago the plan was to give the ball to Fox and let him dissect the defense off the dribble, in the final period last season we saw a lot of threes taken early in the shot-clock resulting in wasted possessions at critical points of the game.
Statistically speaking, Fox should be shooting a lot if he's able to make them at a 40% clip. And to his credit, he seems to have recognized this and shot more of them in the parts of the season when his shot was going in at around a 40% clip and less of them when it wasn't. Where he could adjust in the future is in his situational awareness. Even if the numbers average out to where a 3pt attempt is better than a 2pt attempt in the aggregate, when the score is close and the clock is winding down, the difference between 2 pts and 0 pts is potentially game-breaking. In that situation it's better to get the 2 pts.
Ultimately I guess we're saying the same thing in different words. Nobody is mad about Fox's improved outside shot. The frustration stems more from the over-reliance on off the dribble threes and the ball sticking with one player on the perimeter instead of moving around to the open shooter. I do wonder how much of this stems from our elite shooters being either reluctant to take the shot when it's there (Barnes and Ellis) or losing confidence in their jumper by the second half of the season (Huerter and Murray). This is another area where a healthy and confident Sasha Vezenkov coming off the bench next year could help us. He was one of our better shooters this year and he was under-utilized in that capacity.
I guess I'm just rambling at this point. To address the original topic, I still think the biggest changes need to happen on defense. The offense was good enough -- we outscored 4 of the 6 top-ranked teams in the West this year (Denver, Minnesota, LA Clippers, and Phoenix). Conversely, we allowed more points than all of those top 6 teams except for Dallas. There's no way to know for sure but the decision to jettison Queta and Noel in order to keep JaVale McGee as the primary backup C looks really bad right now. McGee is solid on defense but everything else he does on the floor makes him borderline unplayable. I also can't see us rolling into next season with Kessler Edwards as the only backup SF again unless Mike Brown can be hypnotized into actually playing him. If Monte can find a full size defensive wing and a defensive backup C / starting PF who will both be regular parts of the rotation next year, now we're in business. I have confidence in the rest of the rotation guys to continue to improve on both sides of the ball.
