Did it improve his shooting?
Against the Mavericks w/googles:
He shot 8/13 from the field. 61.5% FG.
He shot 3/6 from 3 pt land. 50% 3pt FG.
He shot 3/6 from the FT stripe. 50% FT.
Brown's shooting overall improved compared to his average this year except for his FT shooting.
I am a believer that Brown just does not have a good, consistent FT routine. Because the rest of his shooting from the field is quite good. In 2017 Jaylen averages 46% from the field and 40% from 3 point overall. Meanwhile his FT percentage dropped from 68% in his rookie year to 59% this year.
