What a spot-on analysis, thanks for linking. No points of disagreement here, as I've long argued that added strength, cutting out midrange jumpers and increasing FG% and shot frequency at the rim will be key to his success in year 2.
I'm less optimistic than James Ham about improvements to his passing ability, as Fox has always been more of a combo in terms of Assist % and A/TO, and this nuance takes a long time plus a combo of special systems + personnel to develop, if possible to improve at all. A speedier system and added strength may help with his assist volume but I also expect the A/TO to not rise >2/1, thus we'll always need passers on the floor with him to help move the ball.
