From what I've seen around different leagues and different levels of PGs, it doesn't matter if the guy can't shoot he'll still take a ridiculous amount of shots and shoot <30%. Don't think its possible to create a solely playmaking PG like Rondo in this game.
You forget that Rondo plays in NBA,where you can say that he has a bad shot relatively to the level of the adversaries outside defenders,not relatively to all the basketball world
A PG like rondo would have 12 on Js and 8 on JR(bad shooting skills againt 15 Od defender) but a good Is and high Od,driving and passing
