Shai is definitely better right now, especially in terms of consistency over an 82 game season. But looking at their respective stats at age 22, Ant is right on track for at least reaching SGA's peak: https://stathead.com/tiny/jquFO
Given the age difference and Ant's enormous room for growth (seriously, he's barely scratching the surface as a playmaker), I would take Ant. But Shai is the sure thing
Why is he still playing??
