Fultz changing his mechanics is the most confusing thing about all this, he was shooting well in summer league from three. It's like he heard the criticisms of Lonzo's shot and thought they were about him, the point of him going 1 was that he could get to the rim or shoot, and he's reluctant to shoot because he's messing with his form. His form at the line in college had a very slight hitch that needed to be sped up, other than that his form wasn't bad and he could have been a solid freethrow shooter just taking more of them.
They need to tell him to change his mechanics back immediately.
