Love Hall, but I think his shot at the NBA is pretty minimal as a PG. I don't think he is quick enough and has a decent handle, but not great. He would have to take some major leaps to be an NBA guy.
He possibly understands the chance is remote, so he will prioritize getting a big NIL bag because getting an NBA contract is unlikely. He is smart, so he may be playing the probabilities here. Don't know his mindset, but like TNT said most NBA players are freakish in their athleticism or skill level/some have both and he is neither of those.
