the answer is no!!
you have to ask yourself "what are point guard skills"? ball handling, good decision making, court awareness, etc. things that a regular basketball player should learn in elementary school. in that sense, BASKETBALL skills can be taught. however, a point guard such as nash, johnson, stockton, kidd, chris paul each have devoted themselves to making others better. thats their game. pass 1st, score 2nd. thats their attitude and thats why all of them are in (will be in) the top tier of assists in NBA history. you can teach how to throw a behind the back pass, or an alley hoop, or an inbetween the legs no look pass; but you cant teach how to do it at the right time. it just has to feel right. and if you're a natural scorer you rarely get that feeling.
to answer your question, we cannot teach douby how to make plays like a chris paul. thats something he has to develop into on his own. there is nothing wrong with a point guard that can score. as long as you can make the right decisions. i think douby will do fine if we give him the playing time
