Sexton is doing fine... He scores at a very high clip and does so efficiently... If he can make a few more simple reads per game that would be great. If not his production and minutes are fine.
If he makes some low hanging improvements in the passing department and if they take the offseason and teach him to play at different speeds I think he could improve quite a bit. His game isn't really super nuanced its hard fast straightline drives. If he gets a slight change of pace he will draw even more fouls and maybe open up other parts of the game.
On a night when JC and Mike went 5/22 we are worried that Sexton made an ill advised layup attempt and missed some free throws.
