To add to the DeAaron Fox bit
I am not that keen on DeAaron Fox. He has to dribble the ball a lot and plays a lot of one-on-one. He is a very good player but not good enough to sacrifice Jaylen Brown for. I need a better individual player to lead that trade package.
Fox is the sort of player that looks far better player on a middling basketball team than he would on a winning team. He doesn't play high level winning basketball (as a star, as a leader). He is more of a stat-padder that looks better than he actually is.
The reasons for this is the lack of high efficiency offensive creation particularly in his own scoring. The dude scores a lot - 21 points a year ago, 25 points a game this year. But he takes a lot of shots to get them. 16 shots and 7 FTs a year ago, 19 shots and 7 FTs this year.
His outside shooting is dodgy at only 30-32% on three pointers. He struggles to space the floor or threaten the defense in PnRs with his pull up jump-shot. He either gets all the way to the rim (or the foul line) or you as an opposing team's defense are happy with whatever jump shot he ends up taking.
This makes him a subpar primary creator and unfit to be taking such a large proportion of his team's shot attempts - at least in terms of high quality winning basketball teams. Like I said, fine for middling basketball teams and why he looks better on such a team.
His lack of outside shooting also reduces his team offense (off ball value) meaning almost all of his offensive value comes from individualistic movements (driving with the ball). So right now, he is a solo type star rather than a team-ball star.
His passing is good but not great. So enough extra value is not created here to live with mediocre jump-shooting, ball-happy dribbling and high shot taking selfishness.
Ultimately, Fox is not a player that moves the W-L column as much as one would expect for a player who is putting up big numbers like he is (25ppg 7apg) + he is the type of player who is being over-glorified on a bad-mediocre team vs how well he would do in a high caliber team.
