The tl;dr of it is that Vassell is a good fit in terms of spacing for Wemby apart from CP3 and Barnes while Castle (who is still not a finished product on shooting), Sochan (poor shooter), and Johnson (a misfit because of sharing the areas that he is good at with Wemby). It also says that Fox seems to have retooled his spots after joining the Spurs (small sample size though).
This article makes it even more imperative that the Spurs move away from Keldon Johnson. And try their best to pry away Cam Johnson from the Nets. Who will be a seamless fit with Wemby. Look at his pristine shot chart -


Here's hoping that the Spurs manage a Top 4 of their own which will help them dangle their other lottery pick and Keldon to get Cam Johnson. It should be an off-season priority. Maybe even given up the 38th pick for this purpose.
