I love the length, but I must admit, I am a little concerned about his lack of quickness and burst.
I feel that Fultz has very deceptive quickness. Because his game is about rocking his opponent to sleep, changing speeds, and then getting by them and finishing with superior body control and length.
He covers ground so quickly with his long strides and suddenly he has a layup or he finishes with his high release point. He's got the agility of a gazelle and operates with great calmness in traffic. The fact that he can constantly finish even with a hand in his face or surrounded by defenders, that makes me think he will do well no matter what. His game is not about out-running defenders but beating them with his movement and ball skills.
An official college court is the same size as an official NBA court so it is apparent to me from watching the videos that he will have no problem covering ground in the NBA as well.
As far as his defensive potential, his superior length is well documented. The question will be his lateral speed and ability to contain more explosive guards at the NBA level. The Celtics will probably get a much better idea of where Fultz stands there once he comes in for workouts.
Still feeling Fultz as the #1 overall pick. He has a very calm demeanor and he should play well with IT, both are Washington alumni and already share a connection.
I see Fultz as the kind of complete all-around offensive player who can score at all 3 levels - short, mid, and 3. Put me down now in writing - he's a guaranteed 20ppg scorer at the NBA level. And you'll see be able to see that production by year 2.
