From what I've seen, the mid/left/right close tendencies also seem to influence how many close shots a player takes during gameplay if the primary close shot tendency is low.
Contested J, Drive tendency, Step Through, Triple Threat shot, etc... lots of ways to influence players taking certain shots.
I remember that I've gotten players to shoot no threes by making sure that all of their 3 point location tendencies (mid/left/right etc) are set to 0. I could be off on that.
