Amari Williams is so peripheral. You barely notice he is even on the floor. Barely involved in offense. Barely involved in defense. Barely involved in rebounding.
He is just there ... doing little to nothing.
----------------------------
Positive signs: He has enough size, quickness and athleticism to make it in the NBA.
Negative signs: He shows no signs of having either the skill or know-how necessary to play in this league. It is not a lack of physical talent. It is a lack of skill & know-how.
