I don't see it happening for this team. It's a niche way to score and you need to build your team specifically for it. The Spurs are built for it and the Warriors were built for it but not so much anymore since the best mid range shooter in the game in Durant is gone. Also I'm not sure what stat he's using that has the Spurs 3rd in offense but I've yet to find anything that has them better than 7th or so.
If you go to basketball reference and look at the team pages. There is a section for shooting where you can line up the players FG% from 3-10ft away from the basket and 10-16ft away. The Kings as a whole were atrocious in comparison at both of those distances. From 3-10ft away, Fox shoots 36% and Hield shoots 24%! The best regular rotation player on the team from 3-10ft was Beli at 44%.
For comparison, Gay, Derozan, Belinelli, Aldridge and Poetl all shot higher from there than our most efficient guy in Beli.
After looking at those stats for the first time, I'm noticing that Fox can really improve his game by either working on the 3-10ft shot or scrapping it all together (I'd prefer if he scrapped it for the most part). He actually takes the 2nd most shots from that area than anywhere else on the floor. In comparison, Hield takes the least shots from 3-10ft than anywhere else on the floor so even though he shoots horribly from there, it doesn't have nearly the impact on his efficiency than it does for Fox.
