all in all i would say set is not the most important factor for what your pg needs. i look like this. if your pg is a true pg, and doesn't score much, pass is significantly more important than bh. if your pg is meant to score a solid amount, bh closes the gap a lot. if your pg is meant to score a crap load, bh might even be more important than pass. what set you run probably affects the bh/pass trade off a lot more for scorers than non scorers, and i honestly am not sure any coach knows which is more important for which. my personal opinion differs from many and i've never heard a consensus.
is that the spd/bh/pass you are projecting him out to or what he has now? what he will be as a junior is a lot more important than what he will be now - but if those are the numbers he is at now, good chance he is going to be a good pg.
