his playmaking is ok... when he goes downhill or off a pick n roll he generally makes the good decision. it just got shadowed by the fact he can't shoot so opponents sag off on him, making it much more difficult for him to create space with dribble penetration. simmons and draymond have similar issues when opponents don't respect their shots. so you really have to be extreme strong in other aspects of your game to make up for your lack of shooting, which unfortunately hasn't been the case for Forrest.
I agree that hughes has good tools to be a good defender, but as of now he's way better in a zone than man-to-man, which is why he looked good tonight but was completely lost on the floor defensively in his past outings.
