Maybe you imagined him looking fast, it wasn't real?
I watched him fairly closely because I agree he has been quiet lately. He didn’t look slow and he did do some good things in terms of board work and maintaining some possession but his hands are a bit off to me and he isn’t meshing with whoever he was playing with. Given how often he is hit knocked down and fouled I think he’s probably getting tired both physically and emotionally. It can’t be easy for a kid to have to carry the hopes of an entire franchise and lose more often than not and your “security blanket” is still out with a lower body injury.
