So far in 2 seasons all Sasha has shown is that he can shoot well anytime except when he's in an actual game. I think Phil last year used the term "11:00 shooter" meaning he's great during warmups but can't deliver at 7:00 which is game time.
Green improved his shot a ton since last year and has true 3pt. range now. He's a no-brainer pick over Sasha if somehow came down to the 2 of them. Sasha has a reputation but can't deliver, Green has shown he can deliver and is a much better defender than Sasha and smarter player too.
