I believe shooting deficiencies are still correctable if the player just has the will to improve that aspect of his game. So it's more of like a personality issue, jerian is still young and his potential is still untapped same can be said of hardaway to an extent.
With practice and time, Jerian should be able to make open shots at a higher percentage enough to demand respect from the opposing team.
But I prefer jerian's play making mind set compared to hardaway's scoring since we already are grooming KP for that role and it looks like he is slowly but surely revealing his shooting is very good.
